DEFINITION OF CLOCK AND CYCLE
q Operation source clock The operation source clock is the source clock to operate this product. In this product, the following clocks are used. * Clock (f(XIN)) by the external ceramic resonator * Clock (f(XIN)) by the external RC oscillation * Clock (f(XIN)) by the external input * Clock (f(RING)) of the on-chip oscillator which is the internal oscillator * Clock (f(XIN)) by the external quartz-crystal oscillation Table Selection of system clock Register MR System clock MR3 MR2 MR1 MR0 0 0 0 0 f(STCK) = f(XIN) 1 f(STCK) = f(RING) 0 1 0 0 f(STCK) = f(XIN)/2 1 f(STCK) = f(RING)/2 1 0 0 0 f(STCK) = f(XIN)/4 1 f(STCK) = f(RING)/4 1 1 0 0 f(STCK) = f(XIN)/8 1 f(STCK) = f(RING)/8 : 0 or 1 Note: The f(RING)/8 is selected after system is released from reset. When on-chip oscillator clock is selected for main clock, set the on-chip oscillator to be operating state.
q System clock (STCK) The system clock is the basic clock for controlling this product. The system clock is selected by the clock control register MR shown as the table below. q Instruction clock (INSTCK) The instruction clock is the basic clock for controlling CPU. The instruction clock (INSTCK) is a signal derived by dividing the system clock (STCK) by 3. The one instruction clock cycle generates the one machine cycle. q Machine cycle The machine cycle is the standard cycle required to execute the instruction.

Notes 1: After system is released from reset, the internal oscillation (on-chip oscillator) is selected for system clock (RG0=0, MR0=1). 2: When the CRCK instruction is executed, the RC oscillation circuit becomes valid. Be careful that the swich of system clock is not executed at oscillation start only by the CRCK instruction execution. In order to start oscillation, setting the main clock f(XIN) oscillation to be valid (MR1=0) is required. (If necessary, generate the oscillation stabilizing wait time by software.) Also, when the main clock (f(XIN)) is selected as system clock, set the main clock f(XIN) oscillation (MR1=0) to be valid, and select main clock f(XIN) (MR0=0). Be careful that the switch of system clock cannot be executed at the same time when main clock oscillation is started. 3: In order to use the external clock input for the main clock, select the ceramic resonance by executing the CMCK instruction at the beggining of software, and then set the main clock (f(XIN)) oscillation to be valid (MR1=0). Until the main clock (f(XIN)) oscillation becomes valid (MR1=0) after ceramic resonance becomes valid, XIN pin is fixed to "H". When an external clock is used, insert a 1 k resistor to XIN pin in series for limits of current. 4: Be sure to select the output structure of ports D0-D5 and the pull-up function of P00-P03 and P10-P13 with every one port. Set the corresponding bits of registers for each port. 5: Be sure to select the output structure of ports P00-P03 and P10-P13 with every two ports. If only one of the two pins is used, leave another one open. 6: The key-on wakeup function is selected with every two bits. When only one of key-on wakeup function is used, considering that the value of key-on wake-up control register K1, set the unused 1-bit to "H" input (turn pull-up transistor ON and open) or "L" input (connect to VSS, or open and set the output latch to "0"). 7: The key-on wakeup function is selected with every two bits. When one of key-on wakeup function is used, turn pull-up transistor of the unused one ON and open. (Note when connecting to VSS and VDD) q Connect the unused pins to VSS and VDD using the thickest wire at the shortest distance against noise.

(1) Arithmetic logic unit (ALU)
The arithmetic logic unit ALU performs 4-bit arithmetic such as 4bit data addition, comparison, AND operation, OR operation, and bit manipulation.
(M(DP)) Addition (A) ALU
(2) Register A and carry flag
Register A is a 4-bit register used for arithmetic, transfer, exchange, and I/O operation. Carry flag CY is a 1-bit flag that is set to "1" when there is a carry with the AMC instruction (Figure 1). It is unchanged with both A n instruction and AM instruction. The value of A0 is stored in carry flag CY with the RAR instruction (Figure 2). Carry flag CY can be set to "1" with the SC instruction and cleared to "0" with the RC instruction.

(3) Registers B and E
Register B is a 4-bit register used for temporary storage of 4-bit data, and for 8-bit data transfer together with register A. Register E is an 8-bit register. It can be used for 8-bit data transfer with register B used as the high-order 4 bits and register A as the low-order 4 bits (Figure 3). Register E is undefined after system is released from reset and returned from the RAM back-up. Accordingly, set the initial value.

(4) Register D
Register D is a 3-bit register. It is used to store a 7-bit ROM address together with register A and is used as a pointer within the specified page when the TABP p, BLA p, or BMLA p instruction is executed. Also, when the TABP p instruction is executed, the high-order 2 bits of the reference data in ROM is stored to the low-order 2 bits of register D, and the contents of the high-order 1 bit of register D is "0". (Figure 4). Register D is undefined after system is released from reset and returned from the RAM back-up. Accordingly, set the initial value.

(5) Stack registers (SKS) and stack pointer (SP)
Stack registers (SKs) are used to temporarily store the contents of program counter (PC) just before branching until returning to the original routine when; * branching to an interrupt service routine (referred to as an interrupt service routine), * performing a subroutine call, or * executing the table reference instruction (TABP p). Stack registers (SKs) are eight identical registers, so that subroutines can be nested up to 8 levels. However, one of stack registers is used respectively when using an interrupt service routine and when executing a table reference instruction. Accordingly, be careful not to over the stack when performing these operations together. The contents of registers SKs are destroyed when 8 levels are exceeded. The register SK nesting level is pointed automatically by 3-bit stack pointer (SP). The contents of the stack pointer (SP) can be transferred to register A with the TASP instruction. Figure 5 shows the stack registers (SKs) structure. Figure 6 shows the example of operation at subroutine call.
Program counter (PC) Executing BM instruction SK0 SK1 SK2 SK3 SK4 SK5 SK6 SK7 Executing RT instruction (SP) = 0 (SP) = 1 (SP) = 2 (SP) = 3 (SP) = 4 (SP) = 5 (SP) = 6 (SP) = 7
Stack pointer (SP) points "7" at reset or returning from RAM back-up mode. It points "0" by executing the first BM instruction, and the contents of program counter is stored in SK0. When the BM instruction is executed after eight stack registers are used ((SP) = 7), (SP) = 0 and the contents of SK0 is destroyed.
Fig. 5 Stack registers (SKs) structure
(6) Interrupt stack register (SDP)
Interrupt stack register (SDP) is a 1-stage register. When an interrupt occurs, this register (SDP) is used to temporarily store the contents of data pointer, carry flag, skip flag, register A, and register B just before an interrupt until returning to the original routine. Unlike the stack registers (SKs), this register (SDP) is not used when executing the subroutine call instruction and the table reference instruction.

Skip flag controls skip decision for the conditional skip instructions and continuous described skip instructions. When an interrupt occurs, the contents of skip flag is stored automatically in the interrupt stack register (SDP) and the skip condition is retained.

(8) Program counter (PC)
Program counter (PC) is used to specify a ROM address (page and address). It determines a sequence in which instructions stored in ROM are read. It is a binary counter that increments the number of instruction bytes each time an instruction is executed. However, the value changes to a specified address when branch instructions, subroutine call instructions, return instructions, or the table reference instruction (TABP p) is executed. Program counter consists of PCH (most significant bit to bit 7) which specifies to a ROM page and PCL (bits 6 to 0) which specifies an address within a page. After it reaches the last address (address 127) of a page, it specifies address 0 of the next page (Figure 7). Make sure that the PCH does not specify after the last page of the built-in ROM.

(9) Data pointer (DP)
Data pointer (DP) is used to specify a RAM address and consists of registers Z, X, and Y. Register Z specifies a RAM file group, register X specifies a file, and register Y specifies a RAM digit (Figure 8). Register Y is also used to specify the port D bit position. When using port D, set the port D bit position to register Y certainly and execute the SD, RD, or SZD instruction (Figure 9). * Note Register Z of data pointer is undefined after system is released from reset. Also, registers Z, X and Y are undefined in the RAM back-up. After system is returned from the RAM back-up, set these registers.

A part of page 1 (addresses 008016 to 00FF16) is reserved for interrupt addresses (Figure 11). When an interrupt occurs, the address (interrupt address) corresponding to each interrupt is set in the program counter, and the instruction at the interrupt address is executed. When using an interrupt service routine, write the instruction generating the branch to that routine at an interrupt address. Page 2 (addresses 010016 to 017F16) is the special page for subroutine calls. Subroutines written in this page can be called from any page with the 1-word instruction (BM). Subroutines extending from page 2 to another page can also be called with the BM instruction when it starts on page 2. ROM pattern (bits 9 to 0) of all addresses can be used as data areas with the TABP p instruction.

DATA MEMORY (RAM)
1 word of RAM is composed of 4 bits, but 1-bit manipulation (with the SB j, RB j, and SZB j instructions) is enabled for the entire memory area. A RAM address is specified by a data pointer. The data pointer consists of registers Z, X, and Y. Set a value to the data pointer certainly when executing an instruction to access RAM (also, set a value after system returns from RAM back-up). Table 2 shows the RAM size. Figure 12 shows the RAM map. * Note Register Z of data pointer is undefined after system is released from reset. Also, registers Z, X and Y are undefined in the RAM back-up. After system is returned from the RAM back-up, set these registers.

INTERRUPT FUNCTION
The interrupt type is a vectored interrupt branching to an individual address (interrupt address) according to each interrupt source. An interrupt occurs when the following 3 conditions are satisfied. * An interrupt activated condition is satisfied (request flag = "1") * Interrupt enable bit is enabled ("1") * Interrupt enable flag is enabled (INTE = "1") Table 3 shows interrupt sources. (Refer to each interrupt request flag for details of activated conditions.)
Table 3 Interrupt sources Priority Interrupt name level 1 External 0 interrupt 2 3 4 5 6 7 8 External 1 interrupt Timer 1 interrupt Timer 2 interrupt Timer 3 interrupt Timer 4 interrupt A/D interrupt Serial I/O interrupt
Activated condition Level change of INT0 pin Level change of INT1 pin Timer 1 underflow Timer 2 underflow Timer 3 underflow Timer 4 underflow Completion of A/D conversion Completion of serial I/O transmit/receive
(1) Interrupt enable flag (INTE)
The interrupt enable flag (INTE) controls whether the every interrupt enable/disable. Interrupts are enabled when INTE flag is set to "1" with the EI instruction and disabled when INTE flag is cleared to "0" with the DI instruction. When any interrupt occurs, the INTE flag is automatically cleared to "0," so that other interrupts are disabled until the EI instruction is executed.
Interrupt address Address 0 in page 1 Address 2 in page 1 Address 4 in page 1 Address 6 in page 1 Address 8 in page 1 Address A in page 1 Address C in page 1 Address E in page 1
(2) Interrupt enable bit
Use an interrupt enable bit of interrupt control registers V1 and V2 to select the corresponding interrupt or skip instruction. Table 4 shows the interrupt request flag, interrupt enable bit and skip instruction. Table 5 shows the interrupt enable bit function.
Table 4 Interrupt request flag, interrupt enable bit and skip instruction Interrupt name External 0 interrupt External 1 interrupt Timer 1 interrupt Timer 2 interrupt Timer 3 interrupt Timer 4 interrupt A/D interrupt Serial I/O interrupt Interrupt request flag EXF0 EXF1 T1F T2F T3F T4F ADF SIOF Skip instruction SNZ0 SNZ1 SNZT1 SNZT2 SNZT3 SNZT4 SNZAD SNZSI Interrupt enable bit V10 V11 V12 V13 V20 V21 V22 V23
(3) Interrupt request flag
When the activated condition for each interrupt is satisfied, the corresponding interrupt request flag is set to "1." Each interrupt request flag is cleared to "0" when either; * an interrupt occurs, or * the next instruction is skipped with a skip instruction. Each interrupt request flag is set when the activated condition is satisfied even if the interrupt is disabled by the INTE flag or its interrupt enable bit. Once set, the interrupt request flag retains set until a clear condition is satisfied. Accordingly, an interrupt occurs when the interrupt disable state is released while the interrupt request flag is set. If more than one interrupt request flag is set when the interrupt disable state is released, the interrupt priority level is as follows shown in Table 3.

(4) Internal state during an interrupt
The internal state of the microcomputer during an interrupt is as follows (Figure 14). * Program counter (PC) An interrupt address is set in program counter. The address to be executed when returning to the main routine is automatically stored in the stack register (SK). * Interrupt enable flag (INTE) INTE flag is cleared to "0" so that interrupts are disabled. * Interrupt request flag Only the request flag for the current interrupt source is cleared to "0." * Data pointer, carry flag, skip flag, registers A and B The contents of these registers and flags are stored automatically in the interrupt stack register (SDP).

Stored in the interrupt stack register (SDP) automatically Fig. 14 Internal state when interrupt occurs
(5) Interrupt processing
When an interrupt occurs, a program at an interrupt address is executed after branching a data store sequence to stack register. Write the branch instruction to an interrupt service routine at an interrupt address. Use the RTI instruction to return from an interrupt service routine. Interrupt enabled by executing the EI instruction is performed after executing 1 instruction (just after the next instruction is executed). Accordingly, when the EI instruction is executed just before the RTI instruction, interrupts are enabled after returning the main routine. (Refer to Figure 13)

Note: "R" represents read enabled, and "W" represents write enabled.
(7) Interrupt sequence
Interrupts only occur when the respective INTE flag, interrupt enable bits (V10-V13, V20-V23), and interrupt request flag are "1." The interrupt actually occurs 2 to 3 machine cycles after the cycle in which all three conditions are satisfied. The interrupt occurs after 3 machine cycles only when the three interrupt conditions are satisfied on execution of other than one-cycle instructions (Refer to Figure 16).

EXTERNAL INTERRUPTS
The 4518 Group has the external 0 interrupt and external 1 interrupt. An external interrupt request occurs when a valid waveform is input to an interrupt input pin (edge detection). The external interrupt can be controlled with the interrupt control registers I1 and I2. Table 7 External interrupt activated conditions Name External 0 interrupt Input pin P30/INT0 Activated condition When the next waveform is input to P30/INT0 pin * Falling waveform ("H""L") * Rising waveform ("L""H") * Both rising and falling waveforms External 1 interrupt P31/INT1 When the next waveform is input to P31/INT1 pin * Falling waveform ("H""L") * Rising waveform ("L""H") * Both rising and falling waveforms I21 I22 Valid waveform selection bit I11 I12

(1) External 0 interrupt request flag (EXF0)
External 0 interrupt request flag (EXF0) is set to "1" when a valid waveform is input to P30/INT0 pin. The valid waveforms causing the interrupt must be retained at their level for 4 clock cycles or more of the system clock (Refer to Figure 16). The state of EXF0 flag can be examined with the skip instruction (SNZ0). Use the interrupt control register V1 to select the interrupt or the skip instruction. The EXF0 flag is cleared to "0" when an interrupt occurs or when the next instruction is skipped with the skip instruction. * External 0 interrupt activated condition External 0 interrupt activated condition is satisfied when a valid waveform is input to P30/INT0 pin. The valid waveform can be selected from rising waveform, falling waveform or both rising and falling waveforms. An example of how to use the external 0 interrupt is as follows. Set the bit 3 of register I1 to "1" for the INT0 pin to be in the input enabled state. Select the valid waveform with the bits 1 and 2 of register I1. Clear the EXF0 flag to "0" with the SNZ0 instruction. Set the NOP instruction for the case when a skip is performed with the SNZ0 instruction. Set both the external 0 interrupt enable bit (V10) and the INTE flag to "1." The external 0 interrupt is now enabled. Now when a valid waveform is input to the P30/INT0 pin, the EXF0 flag is set to "1" and the external 0 interrupt occurs.
(2) External 1 interrupt request flag (EXF1)
External 1 interrupt request flag (EXF1) is set to "1" when a valid waveform is input to P31/INT1 pin. The valid waveforms causing the interrupt must be retained at their level for 4 clock cycles or more of the system clock (Refer to Figure 16). The state of EXF1 flag can be examined with the skip instruction (SNZ1). Use the interrupt control register V1 to select the interrupt or the skip instruction. The EXF1 flag is cleared to "0" when an interrupt occurs or when the next instruction is skipped with the skip instruction. * External 1 interrupt activated condition External 1 interrupt activated condition is satisfied when a valid waveform is input to P31/INT1 pin. The valid waveform can be selected from rising waveform, falling waveform or both rising and falling waveforms. An example of how to use the external 1 interrupt is as follows. Set the bit 3 of register I2 to "1" for the INT1 pin to be in the input enabled state. Select the valid waveform with the bits 1 and 2 of register I2. Clear the EXF1 flag to "0" with the SNZ1 instruction. Set the NOP instruction for the case when a skip is performed with the SNZ1 instruction. Set both the external 1 interrupt enable bit (V11) and the INTE flag to "1." The external 1 interrupt is now enabled. Now when a valid waveform is input to the P31/INT1 pin, the EXF1 flag is set to "1" and the external 1 interrupt occurs.

(4) Notes on External 0 interrupt
Note [1] on bit 3 of register I1 When the input of the INT0 pin is controlled with the bit 3 of register I1 in software, be careful about the following notes. * Depending on the input state of the P30/INT0 pin, the external 0 interrupt request flag (EXF0) may be set when the bit 3 of register I1 is changed. In order to avoid the occurrence of an unexpected interrupt, clear the bit 0 of register V1 to "0" (refer to Figure 18 ) and then, change the bit 3 of register I1. In addition, execute the SNZ0 instruction to clear the EXF0 flag to "0" after executing at least one instruction (refer to Figure 18 ). Also, set the NOP instruction for the case when a skip is performed with the SNZ0 instruction (refer to Figure 18 ).
Note on bit 2 of register I1 When the interrupt valid waveform of the P30/INT0 pin is changed with the bit 2 of register I1 in software, be careful about the following notes. * Depending on the input state of the P30/INT0 pin, the external 0 interrupt request flag (EXF0) may be set when the bit 2 of register I1 is changed. In order to avoid the occurrence of an unexpected interrupt, clear the bit 0 of register V1 to "0" (refer to Figure 20) and then, change the bit 2 of register I1. In addition, execute the SNZ0 instruction to clear the EXF0 flag to "0" after executing at least one instruction (refer to Figure 20). Also, set the NOP instruction for the case when a skip is performed with the SNZ0 instruction (refer to Figure 20).

TIMERS
The 4518 Group has the following timers. * Programmable timer The programmable timer has a reload register and enables the frequency dividing ratio to be set. It is decremented from a setting value n. When it underflows (count to n + 1), a timer interrupt request flag is set to "1," new data is loaded from the reload register, and count continues (auto-reload function).
* Fixed dividing frequency timer The fixed dividing frequency timer has the fixed frequency dividing ratio (n). An interrupt request flag is set to "1" after every n count of a count pulse.

Set the contents of this register through register A with the TPAA instruction. * Timer control register W1 Register W1 controls the selection of timer 1 count auto-stop circuit, and the count operation and count source of timer 1. Set the contents of this register through register A with the TW1A instruction. The TAW1 instruction can be used to transfer the contents of register W1 to register A. * Timer control register W2 Register W2 controls the selection of CNTR0 output, and the count operation and count source of timer 2. Set the contents of this register through register A with the TW2A instruction. The TAW2 instruction can be used to transfer the contents of register W2 to register A. * Timer control register W3 Register W3 controls the selection of the count operation and count source of timer 3 count auto-stop circuit. Set the contents of this register through register A with the TW3A instruction. The TAW3 instruction can be used to transfer the contents of register W3 to register A. * Timer control register W4 Register W4 controls the D7/CNTR1 output, the expansion of "H" interval of PWM output, and the count operation and count source of timer 4. Set the contents of this register through register A with the TW4A instruction. The TAW4 instruction can be used to transfer the contents of register W4 to register A. * Timer control register W5 Register W5 controls the period measurement circuit and target signal for period measurement. Set the contents of this register through register A with the TW5A instruction. The TAW5 instruction can be used to transfer the contents of register W5 to register A. * Timer control register W6 Register W6 controls the count edges of CNTR0 pin and CNTR1 pin, selection of CNTR1 output auto-control circuit and the D6/ CNTR0 pin function. Set the contents of this register through register A with the TW6A instruction. The TAW6 instruction can be used to transfer the contents of register W6 to register A..
(2) Prescaler
Prescaler is an 8-bit binary down counter with the prescaler reload register PRS. Data can be set simultaneously in prescaler and the reload register RPS with the TPSAB instruction. Data can be read from reload register RPS with the TABPS instruction. Stop counting and then execute the TPSAB or TABPS instruction to read or set prescaler data. Prescaler starts counting after the following process; set data in prescaler, and set the bit 0 of register PA to "1." When a value set in reload register RPS is n, prescaler divides the count source signal by n + 1 (n = 0 to 255). Count source for prescaler is the instruction clock (INSTCK). Once count is started, when prescaler underflows (the next count pulse is input after the contents of prescaler becomes "0"), new data is loaded from reload register RPS, and count continues (auto-reload function). The output signal (ORCLK) of prescaler can be used for timer 1, 2, 3, and 4 count sources.
(3) Timer 1 (interrupt function)
Timer 1 is an 8-bit binary down counter with the timer 1 reload register (R1). Data can be set simultaneously in timer 1 and the reload register (R1) with the T1AB instruction. Data can be written to reload register (R1) with the TR1AB instruction. Data can be read from timer 1 with the TAB1 instruction. Stop counting and then execute the T1AB or TAB1 instruction to read or set timer 1 data. When executing the TR1AB instruction to set data to reload register R1 while timer 1 is operating, avoid a timing when timer 1 underflows. Timer 1 starts counting after the following process; set data in timer 1 set count source by bits 0 and 1 of register W1, and set the bit 2 of register W1 to "1." When a value set in reload register R1 is n, timer 1 divides the count source signal by n + 1 (n = 0 to 255). Once count is started, when timer 1 underflows (the next count pulse is input after the contents of timer 1 becomes "0"), the timer 1 interrupt request flag (T1F) is set to "1," new data is loaded from reload register R1, and count continues (auto-reload function). INT0 pin input can be used as the start trigger for timer 1 count operation by setting the bit 0 of register I1 to "1." Also, in this time, the auto-stop function by timer 1 underflow can be performed by setting the bit 3 of register W1 to "1." Timer 1 underflow signal divided by 2 can be output from CNTR0 pin by clearing bit 3 of register W2 to "0" and setting bit 0 of register W6 to "1". The period measurement circuit starts operating by setting bit 2 of register W5 to "1" and timer 1 is used to count the one-period of the target signal for the period measurement. In this time, the timer 1 interrupt request flag (T1F) is not set by the timer 1 underflow signal, it is the flag for detecting the completion of period measurement.

(4) Timer 2 (interrupt function)
Timer 2 is an 8-bit binary down counter with the timer 2 reload register (R2). Data can be set simultaneously in timer 2 and the reload register (R2) with the T2AB instruction. Data can be read from timer 2 with the TAB2 instruction. Stop counting and then execute the T2AB or TAB2 instruction to read or set timer 2 data. Timer 2 starts counting after the following process; set data in timer 2, select the count source with the bits 0 and 1 of register W2, and set the bit 2 of register W2 to "1." When a value set in reload register R2 is n, timer 2 divides the count source signal by n + 1 (n = 0 to 255). Once count is started, when timer 2 underflows (the next count pulse is input after the contents of timer 2 becomes "0"), the timer 2 interrupt request flag (T2F) is set to "1," new data is loaded from reload register R2, and count continues (auto-reload function). Timer 2 underflow signal divided by 2 can be output from CNTR0 pin by setting bit 3 of register W2 to "1" and setting bit 0 of register W6 to "1".
(6) Timer 4 (interrupt function)
Timer 4 is an 8-bit binary down counter with two timer 4 reload registers (R4L, R4H). Data can be set simultaneously in timer 4 and the reload register R4L with the T4AB instruction. Data can be set in the reload register R4H with the T4HAB instruction. The contents of reload register R4L set with the T4AB instruction can be set to timer 4 again with the T4R4L instruction. Data can be read from timer 4 with the TAB4 instruction. Stop counting and then execute the T4AB or TAB4 instruction to read or set timer 4 data. When executing the T4HAB instruction to set data to reload register R4H while timer 4 is operating, avoid a timing when timer 4 underflows. Timer 4 starts counting after the following process; set data in timer 4 set count source by bit 0 of register W4, and set the bit 1 of register W4 to "1." When a value set in reload register R4L is n, timer 4 divides the count source signal by n + 1 (n = 0 to 255). Once count is started, when timer 4 underflows (the next count pulse is input after the contents of timer 4 becomes "0"), the timer 4 interrupt request flag (T4F) is set to "1," new data is loaded from reload register R4L, and count continues (auto-reload function). The PWM signal generated by timer 4 can be output from CNTR1 pin by setting bit 3 of the timer control register W4 to "1". Timer 4 can control the PWM output to CNTR1 pin with timer 3 by setting bit 1 of the timer control register W6 to "1".
(5) Timer 3 (interrupt function)
Timer 3 is an 8-bit binary down counter with the timer 3 reload register (R3). Data can be set simultaneously in timer 3 and the reload register (R3) with the T3AB instruction. Data can be written to reload register (R3) with the TR3AB instruction. Data can be read from timer 3 with the TAB3 instruction. Stop counting and then execute the T3AB or TAB3 instruction to read or set timer 3 data. When executing the TR3AB instruction to set data to reload register R3 while timer 3 is operating, avoid a timing when timer 3 underflows. Timer 3 starts counting after the following process; set data in timer 3 set count source by bits 0 and 1 of register W3, and set the bit 2 of register W3 to "1." When a value set in reload register R3 is n, timer 3 divides the count source signal by n + 1 (n = 0 to 255). Once count is started, when timer 3 underflows (the next count pulse is input after the contents of timer 3 becomes "0"), the timer 3 interrupt request flag (T3F) is set to "1," new data is loaded from reload register R3, and count continues (auto-reload function). INT1 pin input can be used as the start trigger for timer 3 count operation by setting the bit 0 of register I2 to "1." Also, in this time, the auto-stop function by timer 3 underflow can be performed by setting the bit 3 of register W3 to "1."

(7) Period measurement function (Timer 1, period measurement circuit)
Timer 1 has the period measurement circuit which performs timer count operation synchronizing with one cycle of the signal divided by 16 of an on-chip oscillator, D6/CNTR0 pin input, or P30/ INT0 pin input (one cycle, "H", or "L" pulse width at the case of a P30/INT0 pin input). When the target signal for period measurement is set by bits 0 and 1 of register W5, a period measurement circuit is started by setting the bit 2 of register W5 to "1". Then, if a XIN input is set as the count source of a timer 1 and the bit 2 of register W1 is set to "1", timer 1 starts operation. Timer 1 starts operation synchronizing with the falling edge of the target signal for period measurement, and stops count operation synchronizing with the next falling edge (one-period generation circuit). When selecting D6/CNTR0 pin input as target signal for period measurement, the period measurement synchronous edge can be changed into a rising edge by setting the bit 2 of register W6 to "1". When selecting P30/INT0 pin input as target signal for period measurement, period measurement synchronous edge can be changed into a rising edge by setting the bit 2 of register I1 to "1". A timer 1 interrupt request flag (T1F) is set to "1" after completing measurement operation. When a period measurement circuit is set to be operating, timer 1 interrupt request flag (T1F) is not set by timer 1 underflow signal, but turns into a flag which detects the completion of period measurement. In addition, a timer 1 underflow signal can be used as timer 2 count source. Once period measurement operation is completed, even if period measurement valid edge is input next, timer 1 is in a stop state and measurement data is held. When a period measurement circuit is used again, stop a period measurement circuit at once by setting the bit 2 of register W5 to "0", and change a period measurement circuit into a state of operation by setting the bit 2 of register W5 to "1" again. When a period measurement circuit is used, clear bit 0 of register I1 to "0", and set a timer 1 count start synchronous circuit to be "not selected". Start timer operation immediately after operation of a period measurement circuit is started. When the target edge for measurement is input until timer operation is started from the operation of period measurement circuit is started, the count operation is not executed until the timer operation becomes valid. Accordingly, be careful of count data. When data is read from timer, stop the timer and clear bit 2 of register W5 to "0" to stop the period measurement circuit, and then execute the data read instruction. Depending on the state of timer 1, the timer 1 interrupt request flag (T1F) may be set to "1" when the period measurement circuit is stopped by clearing bit 2 of register W5 to "0". In order to avoid the occurrence of an unexpected interrupt, clear the bit 2 of register V1 to "0" (refer to Figure 27) and then, stop the bit 2 of register W5 to "0" to stop the period measurement circuit.
In addition, execute the SNZT1 instruction to clear the T1F flag after executing at least one instruction (refer to Figure 27). Also, set the NOP instruction for the case when a skip is performed with the SNZT1 instruction (refer to Figure 27).

: these bits are not used here. Fig. 27 Period measurement circuit program example When a period measurement circuit is used, select the sufficiently higher-speed frequency than the signal for measurement for the count source of a timer 1. When the target signal for period measurement is D6/CNTR0 pin input, do not select D6/CNTR0 pin input as timer 1 count source. (The XIN input is recommended as timer 1 count source at the time of period measurement circuit use.)
(8) Pulse width measurement function (timer 1, period measurement circuit)
A period measurement circuit can measure "H" pulse width (from rising to falling) or "L" pulse width (from falling to rising) of P30/ INT0 pin input (pulse width measurement function) when the following is set; * Set the bit 0 of register W5 to "0", and set a bit 1 to "1" (target for period measurement circuit: 30/INT0 pin input). * Set the bit 1 of register I1 to "1" (INT0 pin edge detection circuit: both edges detection) The measurement pulse width ("H" or "L") is decided by the period measurement circuit and the P30/INT0 pin input level at the start time of timer operation. At the time of the start of a period measurement circuit and timer operation, "L" pulse width (from falling to rising) when the input level of P30/INT0 pin is "H" or "H" pulse width (from rising to falling) when its level is "L" is measured. When the input of P30/INT0 pin is selected as the target for measurement, set the bit 3 of register I1 to "1", and set the input of INT0 pin to be enabled.

(9) Count start synchronization circuit (timer 1, timer 3)
Timer 1 and timer 3 have the count start synchronous circuit which synchronizes the input of INT0 pin and INT1 pin, and can start the timer count operation. Timer 1 count start synchronous circuit function is selected by setting the bit 0 of register I1 to "1" and the control by INT0 pin input can be performed. Timer 3 count start synchronous circuit function is selected by setting the bit 0 of register I2 to "1" and the control by INT1 pin input can be performed. When timer 1 or timer 3 count start synchronous circuit is used, the count start synchronous circuit is set, the count source is input to each timer by inputting valid waveform to INT0 pin or INT1 pin. The valid waveform of INT0 pin or INT1 pin to set the count start synchronous circuit is the same as the external interrupt activated condition. Once set, the count start synchronous circuit is cleared by clearing the bit I10 or I20 to "0" or reset. However, when the count auto-stop circuit is selected, the count start synchronous circuit is cleared (auto-stop) at the timer 1 or timer 3 underflow.
(11) Timer input/output pin (D6/CNTR0 pin, D7/CNTR1 pin)
CNTR0 pin is used to input the timer 1 count source and output the timer 1 and timer 2 underflow signal divided by 2. CNTR1 pin is used to input the timer 3 count source and output the PWM signal generated by timer 4. The D6/CNTR0 pin function can be selected by bit 0 of register W6. The selection of D7/CNTR1 output signal can be controlled by bit 3 of register W4. When the CNTR0 input is selected for timer 1 count source, timer 1 counts the rising or falling waveform of CNTR0 input. The count edge is selected by the bit 2 of register W6. When the CNTR1 input is selected for timer 3 count source, timer 3 counts the rising or falling waveform of CNTR1 input. The count edge is selected by the bit 3 of register W6.
(12) PWM output function (D7/CNTR1, timer 3, timer 4)
When bit 3 of register W4 is set to "1", timer 4 reloads data from reload register R4L and R4H alternately each underflow. Timer 4 generates the PWM signal (PWMOUT) of the "L" interval set as reload register R4L, and the "H" interval set as reload register R4H. The PWM signal (PWMOUT) is output from CNTR1 pin. When bit 2 of register W4 is set to "1" at this time, the interval (PWM signal "H" interval) set to reload register R4H for the counter of timer 4 is extended for a half period of count source. In this case, when a value set in reload register R4H is n, timer 4 divides the count source signal by n + 1.5 (n = 1 to 255). When this function is used, set "1" or more to reload register R4H. When bit 1 of register W6 is set to "1", the PWM signal output to CNTR1 pin is switched to valid/invalid each timer 3 underflow. However, when timer 3 is stopped (bit 2 of register W3 is cleared to "0"), this function is canceled. Even when bit 1 of a register W4 is cleared to "0" in the "H" interval of PWM signal, timer 4 does not stop until it next timer 4 underflow. When clearing bit 1 of register W4 to "0" to stop timer 4 at the use of PWM output function, avoid a timing when timer 4 underflows.
(10) Count auto-stop circuit (timer 1, timer 3)
Timer 1 has the count auto-stop circuit which is used to stop timer 1 automatically by the timer 1 underflow when the count start synchronous circuit is used. The count auto-stop cicuit is valid by setting the bit 3 of register W1 to "1". It is cleared by the timer 1 underflow and the count source to timer 1 is stopped. This function is valid only when the timer 1 count start synchronous circuit is selected. Timer 3 has the count auto-stop circuit which is used to stop timer 3 automatically by the timer 3 underflow when the count start synchronous circuit is used. The count auto-stop cicuit is valid by setting the bit 3 of register W3 to "1". It is cleared by the timer 3 underflow and the count source to timer 3 is stopped. This function is valid only when the timer 3 count start synchronous circuit is selected.

(13) Timer interrupt request flags (T1F, T2F, T3F, T4F)
Each timer interrupt request flag is set to "1" when each timer underflows. The state of these flags can be examined with the skip instructions (SNZT1, SNZT2, SNZT3, SNZT4). Use the interrupt control register V1, V2 to select an interrupt or a skip instruction. An interrupt request flag is cleared to "0" when an interrupt occurs or when the next instruction is skipped with a skip instruction. The timer 1 interrupt request flag (T1F) is not set by the timer 1 underflow signal, it is the flag for detecting the completion of period measurement.
Depending on the state of timer 1, the timer 1 interrupt request flag (T1F) may be set to "1" when the period measurement circuit is stopped by clearing bit 2 of register W5 to "0". In order to avoid the occurrence of an unexpected interrupt, clear the bit 2 of register V1 to "0" (refer to Figure 28) and then, stop the bit 2 of register W5 to "0" to stop the period measurement circuit. In addition, execute the SNZT1 instruction to clear the T1F flag after executing at least one instruction (refer to Figure 28). Also, set the NOP instruction for the case when a skip is performed with the SNZT1 instruction (refer to Figure 28).
(14) Precautions
Note the following for the use of timers. * Prescaler Stop counting and then execute the TABPS instruction to read from prescaler data. Stop counting and then execute the TPSAB instruction to set prescaler data. * Timer count source Stop timer 1, 2, 3 and 4 counting to change its count source. * Reading the count value Stop timer 1, 2, 3 or 4 counting and then execute the data read instruction (TAB1, TAB2, TAB3, TAB4) to read its data. * Writing to the timer Stop timer 1, 2, 3 or 4 counting and then execute the data write instruction (T1AB, T2AB, T3AB, T4AB) to write its data. * Writing to reload register R1, R3, R4H When writing data to reload register R1, reload register R3 or reload register R4H while timer 1, timer 3 or timer 4 is operating, avoid a timing when timer 1, timer 3 or timer 4 underflows. * Timer 4 Avoid a timing when timer 4 underflows to stop timer 4 at the use of PWM output function. When "H" interval extension function of the PWM signal is set to be "valid", set "1" or more to reload register R4H. * Period measurement function When a period measurement circuit is used, clear bit 0 of register I1 to "0", and set a timer 1 count start synchronous circuit to be "not selected". Start timer operation immediately after operation of a period measurement circuit is started. When the target edge for measurement is input until timer operation is started from the operation of period measurement circuit is started, the count operation is not executed until the timer operation becomes valid. Accordingly, be careful of count data. When data is read from timer, stop the timer and clear bit 2 of register W5 to "0" to stop the period measurement circuit, and then execute the data read instruction.

WATCHDOG TIMER
Watchdog timer provides a method to reset the system when a program run-away occurs. Watchdog timer consists of timer WDT(16-bit binary counter), watchdog timer enable flag (WEF), and watchdog timer flags (WDF1, WDF2). The timer WDT downcounts the instruction clocks as the count source from "FFFF16" after system is released from reset. After the count is started, when the timer WDT underflow occurs (after the count value of timer WDT reaches "000016," the next count pulse is input), the WDF1 flag is set to "1." If the WRST instruction is never executed until the timer WDT underflow occurs (until timer WDT counts 65534), WDF2 flag is set to "1," and the RESET pin outputs "L" level to reset the microcomputer. Execute the WRST instruction at each period of 65534 machine cycle or less by software when using watchdog timer to keep the microcomputer operating normally. When the WEF flag is set to "1" after system is released from reset, the watchdog timer function is valid. When the DWDT instruction and the WRST instruction are executed continuously, the WEF flag is cleared to "0" and the watchdog timer function is invalid. The WEF flag is set to "1" at system reset or RAM back-up mode. The WRST instruction has the skip function. When the WRST instruction is executed while the WDF1 flag is "1", the WDF1 flag is cleared to "0" and the next instruction is skipped. When the WRST instruction is executed while the WDF1 flag is "0", the next instruction is not skipped. The skip function of the WRST instruction can be used even when the watchdog timer function is invalid.
FFFF16 Value of 16-bit timer (WDT) 000016 WDF1 flag
65534 count (Note) WDF2 flag
RESET pin output Reset released WRST instruction executed (skip executed) System reset
After system is released from reset (= after program is started), timer WDT starts count down. When timer WDT underflow occurs, WDF1 flag is set to "1." When the WRST instruction is executed, WDF1 flag is cleared to "0," the next instruction is skipped. When timer WDT underflow occurs while WDF1 flag is "1," WDF2 flag is set to "1" and the watchdog reset signal is output. The output transistor of RESET pin is turned "ON" by the watchdog reset signal and system reset is executed. Note: The number of count is equal to the number of cycle because the count source of watchdog timer is the instruction clock.

page 45 of 157
4518 Group
When the watchdog timer is used, clear the WDF1 flag at the period of 65534 machine cycles or less with the WRST instruction. When the watchdog timer is not used, execute the DWDT instruction and the WRST instruction continuously (refer to Figure 35). The watchdog timer is not stopped with only the DWDT instruction. The contents of WDF1 flag and timer WDT are initialized at the RAM back-up mode. When using the watchdog timer and the RAM back-up mode, initialize the WDF1 flag with the WRST instruction just before the microcomputer enters the RAM back-up state (refer to Figure 36). The watchdog timer function is valid after system is returned from the RAM back-up. When not using the watchdog timer function, execute the DWDT instruction and the WRST instruction continuously every system is returned from the RAM back-up, and stop the watchdog timer function.

A/D CONVERTER (Comparator)
The 4518 Group has a built-in A/D conversion circuit that performs conversion by 10-bit successive comparison method. Table 11 shows the characteristics of this A/D converter. This A/D converter can also be used as an 8-bit comparator to compare analog voltages input from the analog input pin with preset values.

Notes 1: This switch is turned ON only when A/D converter is operating and generates the comparison voltage. 2: Writing/reading data to the comparator register is possible only in the comparator mode (Q13=1). The value of the comparator register is retained even when the mode is switched to the A/D conversion mode (Q13=0) because it is separated from the successive comparison register (AD). Also, the resolution in the comparator mode is 8 bits because the comparator register consists of 8 bits.

(4) A/D conversion completion flag (ADF)
A/D conversion completion flag (ADF) is set to "1" when A/D conversion completes. The state of ADF flag can be examined with the skip instruction (SNZAD). Use the interrupt control register V2 to select the interrupt or the skip instruction. The ADF flag is cleared to "0" when the interrupt occurs or when the next instruction is skipped with the skip instruction.
(5) A/D conversion start instruction (ADST)
A/D conversion starts when the ADST instruction is executed. The conversion result is automatically stored in the register AD.
(6) Operation description
A/D conversion is started with the A/D conversion start instruction (ADST). The internal operation during A/D conversion is as follows: When the A/D conversion starts, the register AD is cleared to "00016." Next, the topmost bit of the register AD is set to "1," and the comparison voltage Vref is compared with the analog input voltage VIN. When the comparison result is Vref < VIN, the topmost bit of the register AD remains set to "1." When the comparison result is Vref > VIN, it is cleared to "0." The 4518 Group repeats this operation to the lowermost bit of the register AD to convert an analog value to a digital value. A/D conversion stops after 2 machine cycles + A/D conversion clock (31 s when f(XIN) = 6.0 MHz in XIN through mode, f(ADCK) = f(INSTCK)/ 6) from the start, and the conversion result is stored in the register AD. An A/D interrupt activated condition is satisfied and the ADF flag is set to "1" as soon as A/D conversion completes (Figure 38).
(2) Operating at A/D conversion mode
The A/D conversion mode is set by setting the bit 3 of register Q1 to "0."
(3) Successive comparison register AD
Register AD stores the A/D conversion result of an analog input in 10-bit digital data format. The contents of the high-order 8 bits of this register can be stored in register B and register A with the TABAD instruction. The contents of the low-order 2 bits of this register can be stored into the high-order 2 bits of register A with the TALA instruction. However, do not execute these instructions during A/D conversion. When the contents of register AD is n, the logic value of the comparison voltage Vref generated from the built-in DA converter can be obtained with the reference voltage VDD by the following formula: Logic value of comparison voltage Vref Vref =
VDD n 1024
n: The value of register AD (n = 0 to 1023)

(8) How to use A/D conversion
How to use A/D conversion is explained using as example in which the analog input from P60/AIN0 pin is A/D converted, and the highorder 4 bits of the converted data are stored in address M(Z, X, Y) = (0, 0, 0), the middle-order 4 bits in address M(Z, X, Y) = (0, 0, 1), and the low-order 2 bits in address M(Z, X, Y) = (0, 0, 2) of RAM. The A/D interrupt is not used in this example. Instruction clock/6 is selected as the A/D converter operation clock. Select the AIN0 pin function with the bit 0 of the register Q2. Select the AIN0 pin function and A/D conversion mode with the register Q1. Also, the instruction clock divided by 6 is selected with the register Q3. (refer to Figure 39) Execute the ADST instruction and start A/D conversion. Examine the state of ADF flag with the SNZAD instruction to determine the end of A/D conversion. Transfer the low-order 2 bits of converted data to the high-order 2 bits of register A (TALA instruction). Transfer the contents of register A to M (Z, X, Y) = (0, 0, 2). Transfer the high-order 8 bits of converted data to registers A and B (TABAD instruction). Transfer the contents of register A to M (Z, X, Y) = (0, 0, 1). Transfer the contents of register B to register A, and then, store into M(Z, X, Y) = (0, 0, 0).

(9) Operation at comparator mode
The A/D converter is set to comparator mode by setting bit 3 of the register Q1 to "1." Below, the operation at comparator mode is described.
(12) Comparator operation start instruction (ADST instruction)
In comparator mode, executing ADST starts the comparator operating. The comparator stops 2 machine cycles + A/D conversion clock f(ADCK) 1 clock after it has started (4 s at f(XIN) = 6.0 MHz in XIN through mode, f(ADCK) = f(INSTCK)/6). When the analog input voltage is lower than the comparison voltage, the ADF flag is set to "1."
(10) Comparator register
In comparator mode, the built-in DA comparator is connected to the 8-bit comparator register as a register for setting comparison voltages. The contents of register B is stored in the high-order 4 bits of the comparator register and the contents of register A is stored in the low-order 4 bits of the comparator register with the TADAB instruction. When changing from A/D conversion mode to comparator mode, the result of A/D conversion (register AD) is undefined. However, because the comparator register is separated from register AD, the value is retained even when changing from comparator mode to A/D conversion mode. Note that the comparator register can be written and read at only comparator mode. If the value in the comparator register is n, the logic value of comparison voltage Vref generated by the built-in DA converter can be determined from the following formula: Logic value of comparison voltage Vref Vref = VDD 256 n
(13) Notes for the use of A/D conversion
* TALA instruction When the TALA instruction is executed, the low-order 2 bits of register AD is transferred to the high-order 2 bits of register A, simultaneously, the low-order 2 bits of register A is "0." * Operation mode of A/D converter Do not change the operating mode (both A/D conversion mode and comparator mode) of A/D converter with the bit 3 of register Q1 while the A/D converter is operating. Clear the bit 2 of register V2 to "0" to change the operating mode of the A/D converter from the comparator mode to A/D conversion mode. The A/D conversion completion flag (ADF) may be set when the operating mode of the A/D converter is changed from the comparator mode to the A/D conversion mode. Accordingly, set a value to the register Q1, and execute the SNZAD instruction to clear the ADF flag.
n: The value of register AD (n = 0 to 255)
(11) Comparison result store flag (ADF)
In comparator mode, the ADF flag, which shows completion of A/D conversion, stores the results of comparing the analog input voltage with the comparison voltage. When the analog input voltage is lower than the comparison voltage, the ADF flag is set to "1." The state of ADF flag can be examined with the skip instruction (SNZAD). Use the interrupt control register V2 to select the interrupt or the skip instruction. The ADF flag is cleared to "0" when the interrupt occurs or when the next instruction is skipped with the skip instruction.

(14) Definition of A/D converter accuracy
The A/D conversion accuracy is defined below (refer to Figure 41). * Relative accuracy Zero transition voltage (V0T) This means an analog input voltage when the actual A/D conversion output data changes from "0" to "1." Full-scale transition voltage (VFST) This means an analog input voltage when the actual A/D conversion output data changes from "1023" to "1022." Linearity error This means a deviation from the line between V0T and VFST of a converted value between V0T and VFST. Differential non-linearity error This means a deviation from the input potential difference required to change a converter value between V0T and VFST by 1 LSB at the relative accuracy. * Absolute accuracy This means a deviation from the ideal characteristics between 0 to VDD of actual A/D conversion characteristics.
Vn: Analog input voltage when the output data changes from "n" to "n+1" (n = 0 to 1022) * 1LSB at relative accuracy VFST-V0T (V) 1022 VDD 1024

SERIAL INTERFACE
The 4518 Group has a built-in clock synchronous serial I/O which can serially transmit or receive 8-bit data. Serial I/O consists of; * serial I/O register SI * serial I/O control register J1 * serial I/O transmit/receive completion flag (SIOF) * serial I/O counter Registers A and B are used to perform data transfer with internal CPU, and the serial I/O pins are used for external data transfer. The pin functions of the serial I/O pins can be set with the register J1.

(1) Serial I/O register SI
Serial I/O register SI is the 8-bit data transfer serial/parallel conversion register. Data can be set to register SI through registers A and B with the TSIAB instruction. The contents of register A is transmitted to the low-order 4 bits of register SI, and the contents of register B is transmitted to the high-order 4 bits of register SI. During transmission, each bit data is transmitted LSB first from the lowermost bit (bit 0) of register SI, and during reception, each bit data is received LSB first to register SI starting from the topmost bit (bit 7). When register SI is used as a work register without using serial I/O, do not select the SCK pin.
(3) Serial I/O start instruction (SST)
When the SST instruction is executed, the SIOF flag is cleared to "0" and then serial I/O transmission/reception is started.
(4) Serial I/O control register J1
Register J1 controls the synchronous clock, P20/SCK, P21/SOUT and P22/SIN pin function. Set the contents of this register through register A with the TJ1A instruction. The TAJ1 instruction can be used to transfer the contents of register J1 to register A.
(2) Serial I/O transmit/receive completion flag (SIOF)
Serial I/O transmit/receive completion flag (SIOF) is set to "1" when serial data transmission or reception completes. The state of SIOF flag can be examined with the skip instruction (SNZSI). Use the interrupt control register V2 to select the interrupt or the skip instruction. The SIOF flag is cleared to "0" when the interrupt occurs or when the next instruction is skipped with the skip instruction.

(1) Power-on reset
Reset can be automatically performed at power on (power-on reset) by the built-in power-on reset circuit. When the built-in power-on reset circuit is used, the time for the supply voltage to rise from 0 V until the value of supply voltage reaches the minimum operating voltage must be set to 100 s or less.
If the rising time exceeds 100 s, connect a capacitor between the RESET pin and VSS at the shortest distance, and input "L" level to RESET pin until the value of supply voltage reaches the minimum operating voltage.

RAM BACK-UP MODE
The 4518 Group has the RAM back-up mode. When the EPOF and POF instructions are executed continuously, system enters the RAM back-up state. The POF instruction is equal to the NOP instruction when the EPOF instruction is not executed before the POF instruction. As oscillation stops retaining RAM, the function of reset circuit and states at RAM back-up mode, current dissipation can be reduced without losing the contents of RAM. Table 18 shows the function and states retained at RAM back-up. Figure 53 shows the state transition.

(1) Identification of the start condition
Warm start (return from the RAM back-up state) or cold start (return from the normal reset state) can be identified by examining the state of the RAM back-up flag (P) with the SNZP instruction.
(2) Warm start condition
When the external wakeup signal is input after the system enters the RAM back-up state by executing the EPOF and POF instructions continuously, the CPU starts executing the program from address 0 in page 0. In this case, the P flag is "1."
(3) Cold start condition
The CPU starts executing the program from address 0 in page 0 when; * reset pulse is input to RESET pin, or * reset by watchdog timer is performed, or * voltage drop detection circuit detects the voltage drop, or * SRST instruction is executed. In this case, the P flag is "0."
Notes 1:"O" represents that the function can be retained, and "" represents that the function is initialized. Registers and flags other than the above are undefined at RAM back-up, and set an initial value after returning. 2: The stack pointer (SP) points the level of the stack register and is initialized to "7" at RAM back-up. 3: The state of the timer is undefined. 4: Initialize the watchdog timer with the WRST instruction, and then execute the POF instruction. 5: The valid/invalid of the voltage drop detection circuit can be controlled only by VDCE pin.

CLOCK CONTROL
The clock control circuit consists of the following circuits. * On-chip oscillator (internal oscillator) * Ceramic resonator * RC oscillation circuit * Quartz-crystal oscillation circuit * Multi-plexer (clock selection circuit) * Frequency divider * Internal clock generating circuit The system clock and the instruction clock are generated as the source clock for operation by these circuits. Figure 56 shows the structure of the clock control circuit. The 4518 Group operates by the on-chip oscillator clock (f(RING)) which is the internal oscillator after system is released from reset. Also, the ceramic resonator, the RC oscillation or quartz-crystal oscillator can be used for the main clock (f(XIN)) of the 4518 Group. The CMCK instruction, CRCK instruction or CYCK instruction is executed to select the ceramic resonator, RC oscillator or quartz-crystal oscillator respectively.
The CMCK, CRCK, and CYCK instructions can be used only to select main clock (f(XIN)). In this time, the start of oscillation and the switch of system clock are not performed. The oscillation start/stop of main clock f(XIN) is controlled by bit 1 of register MR. The system clock is selected by bit 0 of register MR. The oscillation start/stop of on-chip oscillator is controlled by register RG. The oscillation circuit by the CMCK, CRCK or CYCK instruction can be selected only at once. The oscillation circuit corresponding to the first executed one of these instructions is valid. Execute the main clock (f(XIN)) selection instruction (CMCK, CRCK or CYCK instruction) in the initial setting routine of program (executing it in address 0 in page 0 is recommended). When the CMCK, CRCK, and CYCK instructions are never executed, main clock (f(XIN)) cannot be used and system can be operated only by on-chip oscillator. The no operated clock source (f(RING)) or (f(XIN)) cannot be used for the system clock. Also, the clock source (f(RING) or f(XIN)) selected for the system clock cannot be stopped.

(1) Main clock generating circuit (f(XIN))
The ceramic resonator, RC oscillation or quartz-crystal oscillator can be used for the main clock of this MCU. After system is released from reset, the MCU starts operation by the clock output from the on-chip oscillator which is the internal oscillator. When the ceramic resonator is used, execute the CMCK instruction. When the RC oscillation is used, execute the CRCK instruction. When the quartz-crystal oscillator is used, execute the CYCK instruction. The oscillation start/stop of main clock f(XIN) is controlled by bit 1 of register MR. The system clock is selected by bit 0 of register MR. The oscillation circuit by the CMCK, CRCK or CYCK instruction can be selected only at once. The oscillation circuit corresponding to the first executed one of these instructions is valid. Execute the CMCK, CRCK or CYCK instruction in the initial setting routine of program (executing it in address 0 in page 0 is recommended). Also, when the CMCK, CRCK or CYCK instruction is not executed in program, this MCU operates by the on-chip oscillator.

(2) On-chip oscillator operation
When the MCU operates by the on-chip oscillator as the main clock (f(XIN)) without using the ceramic resonator, RC oscillator or quartz-crystal oscillation, leave XIN pin and XOUT pin open (Figure 58). The clock frequency of the on-chip oscillator depends on the supply voltage and the operation temperature range. Be careful that variable frequencies when designing application products.

(6) External clock
When the external clock signal for the main clock (f(XIN)) is used, connect the clock source to XIN pin and XOUT pin open. In program, after the CMCK instruction is executed, set main clock (f(XIN)) oscillation start to be enabled (MR1=0). For this product, when RAM back-up mode and main clock (f(XIN)) stop (MR1=1), XIN pin is fixed to "H" in order to avoid the through current by floating of internal logic. The XIN pin is fixed to "H" until main clock (f(XIN)) oscillation starts to be valid (MR1=0) by the CMCK instruction from reset state. Accordingly, when an external clock is used, connect a 1 k or more resistor to XIN pin in series to limit of current by competitive signal.

LIST OF PRECAUTIONS
Noise and latch-up prevention Connect a capacitor on the following condition to prevent noise and latch-up; * connect a bypass capacitor (approx. 0.1 F) between pins VDD and VSS at the shortest distance, * equalize its wiring in width and length, and * use relatively thick wire. In the One Time PROM version, CNVSS pin is also used as VPP pin. Accordingly, when using this pin, connect this pin to VSS through a resistor about 5 k (connect this resistor to CNVSS/ VPP pin as close as possible). Register initial values 1 The initial value of the following registers are undefined after system is released from reset. After system is released from reset, set initial values. * Register Z (2 bits) * Register D (3 bits) * Register E (8 bits) Register initial values 2 The initial value of the following registers are undefined at RAM backup. After system is returned from RAM back-up, set initial values. * Register Z (2 bits) * Register X (4 bits) * Register Y (4 bits) * Register D (3 bits) * Register E (8 bits) Stack registers (SKS) Stack registers (SKs) are eight identical registers, so that subroutines can be nested up to 8 levels. However, one of stack registers is used respectively when using an interrupt service routine and when executing a table reference instruction. Accordingly, be careful not to over the stack when performing these operations together.
Multifunction * The input/output of P30 and P31 can be used even when INT0 and INT1 are selected. * The input of ports P20-P22 can be used even when SIN, SOUT and SCK are selected. * The input/output of D6 can be used even when CNTR0 (input) is selected. * The input of D6 can be used even when CNTR0 (output) is selected. * The input/output of D7 can be used even when CNTR1 (input) is selected. * The input of D7 can be used even when CNTR1 (output) is selected. Prescaler Stop counting and then execute the TABPS instruction to read from prescaler data. Stop counting and then execute the TPSAB instruction to set prescaler data. Timer count source Stop timer 1, 2, 3 and 4 counting to change its count source. Reading the count value Stop timer 1, 2, 3 or 4 counting and then execute the data read instruction (TAB1, TAB2, TAB3, TAB4) to read its data. Writing to the timer Stop timer 1, 2, 3 or 4 counting and then execute the data write instruction (T1AB, T2AB, T3AB, T4AB) to write its data.
10
Writing to reload register R1, R3, R4H When writing data to reload register R1, reload register R3 or reload register R4H while timer 1, timer 3 or timer 4 is operating, avoid a timing when timer 1, timer 3 or timer 4 underflows. Timer 4 Avoid a timing when timer 4 underflows to stop timer 4 at the use of PWM output function. When "H" interval extension function of the PWM signal is set to be "valid", set "1" or more to reload register R4H.

Watchdog timer * The watchdog timer function is valid after system is released from reset. When not using the watchdog timer function, execute the DWDT instruction and the WRST instruction continuously, and clear the WEF flag to "0" to stop the watchdog timer function. * The watchdog timer function is valid after system is returned from the RAM back-up state. When not using the watchdog timer function, execute the DWDT instruction and the WRST instruction continuously every system is returned from the RAM back-up state, and stop the watchdog timer function. * When the watchdog timer function and RAM back-up function are used at the same time, execute the WRST instruction before system enters into the RAM back-up state and initialize the flag

Period measurement circuit When a period measurement circuit is used, clear bit 0 of register I1 to "0", and set a timer 1 count start synchronous circuit to be "not selected". Start timer operation immediately after operation of a period measurement circuit is started. When the edge for measurement is input until timer operation is started from the operation of period measurement circuit is started, the count operation is not executed until the timer operation becomes valid. Accordingly, be careful of count data. When data is read from timer, stop the timer and clear bit 2 of register W5 to "0" to stop the period measurement circuit, and then execute the data read instruction. Depending on the state of timer 1, the timer 1 interrupt request flag (T1F) may be set to "1" when the period measurement circuit is stopped by clearing bit 2 of register W5 to "0". In order to avoid the occurrence of an unexpected interrupt, clear the bit 2 of register V1 to "0" (refer to Figure 65) and then, stop the bit 2 of register W5 to "0" to stop the period measurement circuit. In addition, execute the SNZT1 instruction to clear the T1F flag after executing at least one instruction (refer to Figure 65). Also, set the NOP instruction for the case when a skip is performed with the SNZT1 instruction (refer to Figure 65). While a period measurement circuit is operating, the timer 1 interrupt request flag (T1F) is not set by the timer 1 underflow signal, it is the flag for detecting the completion of period measurement. When a period measurement circuit is used, select the sufficiently higher-speed frequency than the signal for measurement for the count source of a timer 1. When the signal for period measurement is D6/CNTR0 pin input, do not select D6/CNTR0 pin input as timer 1 count source. (The XIN input is recommended as timer 1 count source at the time of period measurement circuit use.) When the input of P30/INT0 pin is selected for measurement, set the bit 3 of a register I1 to "1", and set the input of INT0 pin to be enabled.

P30/INT0 pin Note [1] on bit 3 of register I1 When the input of the INT0 pin is controlled with the bit 3 of register I1 in software, be careful about the following notes. * Depending on the input state of the P30/INT0 pin, the external 0 interrupt request flag (EXF0) may be set when the bit 3 of register I1 is changed. In order to avoid the occurrence of an unexpected interrupt, clear the bit 0 of register V1 to "0" (refer to Figure 66 ) and then, change the bit 3 of register I1.

18 A/D converter-1 * When the TALA instruction is executed, the low-order 2 bits of register AD is transferred to the high-order 2 bits of register A, simultaneously, the low-order 2 bits of register A is "0." * Do not change the operating mode (both A/D conversion mode and comparator mode) of A/D converter with the bit 3 of register Q1 while the A/D converter is operating. * Clear the bit 2 of register V2 to "0" to change the operating mode of the A/D converter from the comparator mode to A/D conversion mode. * The A/D conversion completion flag (ADF) may be set when the operating mode of the A/D converter is changed from the comparator mode to the A/D conversion mode. Accordingly, set a value to the register Q1, and execute the SNZAD instruction to clear the ADF flag.

A/D converter-2 Each analog input pin is equipped with a capacitor which is used to compare the analog voltage. Accordingly, when the analog voltage is input from the circuit with high-impedance and, charge/ discharge noise is generated and the sufficient A/D accuracy may not be obtained. Therefore, reduce the impedance or, connect a capacitor (0.01 F to 1 F) to analog input pins (Figure 73). When the overvoltage applied to the A/D conversion circuit may occur, connect an external circuit in order to keep the voltage within the rated range as shown the Figure 74. In addition, test the application products sufficiently.

POF instruction When the POF instruction is executed continuously after the EPOF instruction, system enters the RAM back-up state. Note that system cannot enter the RAM back-up state when executing only the POF instruction. Be sure to disable interrupts by executing the DI instruction before executing the EPOF instruction and the POF instruction continuously. Program counter Make sure that the PC does not specify after the last page of the built-in ROM. Power-on reset When the built-in power-on reset circuit is used, the time for the supply voltage to rise from 0 V to the value of supply voltage or more must be set to 100 s or less. If the rising time exceeds 100 s, connect a capacitor between the RESET pin and VSS at the shortest distance, and input "L" level to RESET pin until the value of supply voltage reaches the minimum operating voltage. Clock control Execute the main clock (f(XIN)) selection instruction (CMCK, CRCK or CYCK instruction) in the initial setting routine of program (executing it in address 0 in page 0 is recommended). The oscillation circuit by the CMCK, CRCK or CYCK instruction can be selected only at once. The oscillation circuit corresponding to the first executed one of these instructions is valid. The CMCK, CRCK, and CYCK instructions can be used only to select main clock (f(XIN)). In this time, the start of oscillation and the switch of system clock are not performed. When the CMCK, CRCK, and CYCK instructions are never executed, main clock (f(XIN)) cannot be used and system can be operated only by on-chip oscillator. The no operated clock source (f(RING)) or (f(XIN)) cannot be used for the system clock. Also, the clock source (f(RING) or f(XIN)) selected for the system clock cannot be stopped. On-chip oscillator The clock frequency of the on-chip oscillator depends on the supply voltage and the operation temperature range. Be careful that variable frequencies when designing application products. When considering the oscillation stabilize wait time at the switch of clock, be careful that the variable frequency of the on-chip oscillator clock.
25
21
External clock When the external clock signal for the main clock (f(XIN)) is used, connect the clock source to XIN pin and XOUT pin open. In program, after the CMCK instruction is executed, set main clock (f(XIN)) oscillation start to be enabled (MR1=0). For this product, when RAM back-up mode and main clock (f(XIN)) stop (MR1=1), XIN pin is fixed to "H" in order to avoid the through current by floating of internal logic. The XIN pin is fixed to "H" until main clock (f(XIN)) oscillation start to be valid (MR1=0) by the CMCK instruction from reset state. Accordingly, when an external clock is used, connect a 1 k or more resistor to XIN pin in series to limit of current by competitive signal. Electric Characteristic Differences Between Mask ROM and One Time PROM Version MCU There are differences in electric characteristics, operation margin, noise immunity, and noise radiation between Mask ROM and One Time PROM version MCUs due to the difference in the manufacturing processes. When manufacturing an application system with the One time PROM version and then switching to use of the Mask ROM version, please perform sufficient evaluations for the commercial samples of the Mask ROM version. Note on Power Source Voltage When the power source voltage value of a microcomputer is less than the value which is indicated as the recommended operating conditions, the microcomputer does not operate normally and may perform unstable operation. In a system where the power source voltage drops slowly when the power source voltage drops or the power supply is turned off, reset a microcomputer when the supply voltage is less than the recommended operating conditions and design a system not to cause errors to the system by this unstable operation.

Note : Some instructions of the 4518 Group has the skip function to unexecute the next described instruction. The 4518 Group just invalidates the next instruction when a skip is performed. The contents of program counter is not increased by 2. Accordingly, the number of cycles does not change even if skip is not performed. However, the cycle count becomes "1" if the TABP p, RT, or RTS instruction is skipped.

Loads the value n in the immediate field to register A. When the LA instructions are continuously coded and executed, only the first LA instruction is executed and other LA instructions coded continuously are skipped. Transfers bits 9 and 8 to register D, bits 7 to 4 to register B and bits 3 to 0 to register A. These bits 7 to 0 are the ROM pattern in ad-dress (DR2 DR1 DR0 A3 A2 A1 A0)2 specified by registers A and D in page p. When this instruction is executed, be careful not to over the stack because 1 stage of stack register is used.

BUILT-IN PROM VERSION
In addition to the mask ROM versions, the 4518 Group has the One Time PROM versions whose PROMs can only be written to and not be erased. The built-in PROM version has functions similar to those of the mask ROM versions, but it has PROM mode that enables writing to built-in PROM. Table 23 Product of built-in PROM version PROM size Part number ( 10 bits) M34518E8FP 8192 words M34518E8SP 8192 words
Table 23 shows the product of built-in PROM version. Figure 75 shows the pin configurations of built-in PROM versions. The One Time PROM version has pin-compatibility with the mask ROM version.

(1) PROM mode
The built-in PROM version has a PROM mode in addition to a normal operation mode. The PROM mode is used to write to and read from the built-in PROM. In the PROM mode, the programming adapter can be used with a general-purpose PROM programmer to write to or read from the built-in PROM as if it were M5M27C256K. Programming adapter is listed in Table 24. Contact addresses at the end of this data sheet for the appropriate PROM programmer. * Writing and reading of built-in PROM Programming voltage is 12.5 V. Write the program in the PROM of the built-in PROM version as shown in Figure 76.

(2) Notes on handling
A high-voltage is used for writing. Take care that overvoltage is not applied. Take care especially at turning on the power. For the One Time PROM version shipped in blank, Renesas Technology Corp. does not perform PROM writing test and screening in the assembly process and following processes. In order to improve reliability after writing, performing writing and test according to the flow shown in Figure 77 before using is recommended (Products shipped in blank: PROM contents is not written in factory when shipped).

(3) E l e c t r i c C h a r a c t e r i s t i c D i f f e r e n c e s Between Mask ROM and One TIme PROM Version MCU
There are differences in electric characteristics, operation margin, noise immunity, and noise radiation between Mask ROM and One Time PROM version MCUs due to the difference in the manufacturing processes. When manufacturing an application system with the One Time PROM version and then switching to use of the Mask ROM version, please perform sufficient evaluations for the commercial samples of the Mask ROM version.
Writing with PROM programmer
Screening (Leave at 150 C for 40 hours) (Note)
Verify test with PROM programmer
Function test in target device Note: Since the screening temperature is higher than storage temperature, never expose the microcomputer to 150 C exceeding 100 hours.
