ANALOG INPUT
ITALIAN TECHNOLOGY
One analog input is available on signal MM PIN 33, it has been connected through a specific circuitery that allows to acquire the analog signal directly or divided by 4.
OPTOCOUPLED DIGITAL INPUT LINES The card features 16 NPN/PNP inputs connected to two quick release screw terminal connectors that are directly acquired by 16 I/O lines of 40 pins socket through a galvanically isolated interface. These lines are visualized by specific LEDs and have been selected to be able to take advantage completely of eventual grifo(R) Mini Module internal peripherals, in such case the inputs can generate interrupts, be counted by hardware counters, etc. Optocoupled inputs are supplied by a specific voltage called +Vopto generated on board by a specific circuitery separated from +5 Vdc generation circuitery.
SERIAL COMMUNICATION GMB HR168 features one AMP 4+4 connector (CN6) dedicated to serial communication. By hardware it is possible to select the electric protocol, through a comfortable set of jumpers and drivers to install. In detail line can be not buffered (this means to connect signals MM PIN 9 and MM PIN 10 directly to CN6) or buffered in current loop, RS 232, RS 422 or RS 485; in these last two cases also abilitation and direction of line can be defined using signals MM PIN 17 or MM PIN 30. In case a grifo(R) Mini Module is installed, protocols TTL and RS 232 are immedatly available. Please remark that by default the board is provided without drivers, so any configuration must be specified in the order. For further information about serial communication please refer to paragraph: "CONNECTIONS" and "SERIAL COMMUNICATION SELECTION".
I2C BUS LINES GMB HR168 is provided with one connector (CN8) dedicated to I2C BUS, connected to two signals of the 40 pins socket, MM PIN 12 and MM PIN 13, each provided with a 4.7 k pull-up. This kind of interface allows to connect devices featuring the same communication standard, to easily improve the system performances. Connector has been designed to allow both external and internal connections and satisfy any need of the user. A wide set of software examples explains the management of most common I2C BUS peripherals like A/D and D/A converters, display drivers, memories, temperature sensors, etc. GMB HR168 can be ordered with a Real Time Clock provided with 256 bytes of SRAM already installed (option .RTC), in such case the slave address A0H is already taken by this peripheral, eventual third part hardware cannot use it, in addition a grifo(R) Mini Module provided with its own Real Time Clock cannot be installed for the same reason.

MINI MODULE By Mini Module it is meant the component installed in the 40 pins socket ZC1 that decides the functionality of all board signals. Such component is also in condition to take control of all on board resources and can be In-Circuit programmale, e. g. using a boot loader on serial interface, like for grifo(R) Mini Modules. GMB HR 168 has been designed to accept all 28 or 40 pins grifo(R) Mini Modules or any hardware that can fit in a standard 40 pins 600 mils DIP socket. For further information please refer to description of socket ZC1 in the chapter dedicated to connectors and to chapter "PERIPHERAL DEVICES SOFTWARE DESCRIPTION". Every combination GMB HR 168 + 28 or 40 pins grifo(R) Mini Module is a separated item on our listing, in addition each grifo(R) Mini Module has specific features (e. g. different size of FLASH memory, number of digital I/O signals, etc.), for this reason each combination is described by its own manual. If a combination GMB HR 168 + grifo(R) Mini Module has been ordered, it will be delivered already installed, configured and ready for use.
I/O TTL SIGNALS GMB HR168 features up to 5 digital I/O TTL signals of 40 pins socket connected to a specific AMP 4+4 connector (CN7). In case a grifo(R) Mini Module or the optional Real Time Clock is installed, some of these features become available on CN7: PWM line from CPU internal PCA to generate an analog signal, count signal from CPU internal 16 bit Timer Counter, etc.
DIGITAL RELAYS OUTPUTS The board is provided with 8 relays outputs 4 A, normally open, whose status is visualized by 8 LEDs. Each line is driven directly by a signal of the 40 pins socket, buffered through a specific driver and connected to a comfortable quick release screw terminal connector to easy interface to the field signals. In this casea grifo(R) Mini Module is installed, it is possible to take advantage of internal peripherals, like PCAs, that allow to generate timings and developed funcitons.

POWER SUPPLY SECTION
ITALIAN TECHNOLOGY
GMB HR168 is provided with an efficent switching power supply section, that provides supply +5 Vdc voltage needed by logic and output circuits, in any condition of input load and voltage. A second section is present and generates the rectified voltage +Vopto, allowing to use the optocoupled inputs simply closing its contact with the respective common terminal. This latter section requires a separated power source. The board features components and circuits designed to reduce consumptions and to reduce noise sensibility. Remarkable is protection circuit based on TransZorbTM that avoids damages due to incorrect voltages. To supply optocouplers of galvanically isolated sections a voltage between 12/24 Vdc is needed. For further information please refer to chapter "ELECTRIC FEATURES" and paragraph "SUPPLY VOLTAGES".
TELECONTROL FIRMWARE The Mini Module installed on GMB HR168 can be provided with a telecontrol firmware; such firmwares allow to manage all the board resources through a set of commands to send to the serial line. Taking advantage of these firmwares make possible to use well developed commands that solve fundamental problems of automation like impulse count, wave from generation, debounced input acquisition, Real Time Clock managentent, etc. For grifo(R) Mini Module, Master Slave communication mode is supported; this allows to remote single modules also at great distance, to build a telecontrol network driven by a unique master unit (PC, PLC, GPC(R), etc.). By now, some standard protocols like ALB x84 (ABACO(R) Link BUS) and MODBUS are available, anyway new protocols can be developed on specific request of the customer. Please contact grifo(R) for further information.

FIGURE 14: CURRENT LOOP NETWORK CONNECTION EXAMPLE Possible Current Loop connections are two: 2 wires and 4 wires. These connections are shown in figures 13/15 where it is possible to see the voltage for VCL and the resistances for current limitation (R). The supply voltage varies in compliance with the number of connected devices and voltage drop on the connection cable. The choice of the values for these components must be done cosidering that: - circulation of a 20 mA current must be guaranteed; - potential drop on each transmitter is about 2.35 V with a 20 mA current; - potential drop on each receiver is about 2.52 V cwith a 20 mA current; - in case of shortciruit each transmitter must dissipate at most 125 mW; - in case of shortciruit each receiver must dissipate at most 90 mW.

INTERRUPTS
ITALIAN TECHNOLOGY
Interrupts management depends completely on hardware installed in ZC1, in fact it's this latter to determine which signals are interrupts. If a grifo(R) Mini Module is installed, several interrupt sources are available, depending on which model is used. Please refer to specific manual for further information.
I/O CONNECTION To prevent possible connecting problems between GMB HR168 and the external systems, the user has to read carefully the previous paragraph information and he must follow these instrunctions: - For RS 232, RS 422, RS 485, Current Loop and I2C BUSsignals the user must follow the standard rules of each one of these protocols, I2C BUS signals are also provided with 4.7 k pull up. - For all TTL signals the user must follow the rules of this electric standard. The connected digital signal must be always referred to card digital ground and if an electric insulation is necessary, then an opto coupled interface must be connected. For TTL signals, the 0V level corresponds to logic state 0, while 5V level corrisponds to logic state 1. - The analog inputs (A/D Converter section) on CN7 is provided with filtering capacitors that warrant more stability on the signal to acquire and lower the cut-off frequency. It is also possible to connect a voltage divider that divides by 4 the signal amplitude. - Optocoupled input signals can be configured as NPN or PNP through jumpers J1 and J2, these jumpers must be moved together. In detail, if inputs are configured as NPN, positive voltage is present on input pins (INx-1, INy-2) and ground is present on the common pins (COM1 and COM2), while if the inputs are configured as PNP the situation is reversed, this means ground on input pins and positive signal on common pins. - Relays outputs must be connected directly to the load to drive (remote control switches, power relays, etc.). Board contact is normally open and can bear 5 A up to 30 Vdc. To drive load with different supplies, different COMMONS for the groups of relays are available.

POWER SUPPLY
ITALIAN TECHNOLOGY
GMB HR168 is provided with an efficent circuitery that solves in a comfortable and efficent way the problem to supply the card in any condition of use. Here follow the volages required by the card: +V opto: Provides power supply to optocouplers of board input section; input voltage must be in the range 9/28 Vdc 5% or 9/23Vac 5% and must be provided on connector CN5 through pins 1 and 2, connecting pin 2 to the positive terminal of external power supply and pin 1 to its ground terminal, if it is direct voltage. Vac, +Vdc pow, GND: Provide power supply to control logic and to output section of the board through the on board switching power supply; input voltage must be in the range 10/38Vdc 5% or 8/23Vac 5% and must be provided though puns 3 and 4 of CN5 (in case of Vdc, pin 4 must be connected to positive terminal). This allows to supply the cards using standard devices of industrial sector like transfrmers, batteries, solar cells, etc. If external loads must be supplied, a +5 Vdc voltage can be fetched from pins 1 and 7 of CN6, CN7 or pins 1 and 4 of CN8. Please remark that on board switching power supply is provided with single diode rectifier, so in case of Vdc supply, all ground signals (GND) of the card are at the same potential.
To warrant highest immunity against noise and so a correct working of the cards, it is essential that these two voltages are galvanically isolated In order to obtain this power supply EXPS-2 can be ordered. This device performs galvanic isolation starting from mains power supply. GMB HR168 features a TransZorbTM-based protection circuit to avoid damages from incorrect tensions and break-down of power supply section. On board power supply is visualized through a LED on the bottom left corner. Current available to supply external loads using +5 Vdc is less than: 1000 mA - current absorbed by GMB HR168 - current absorbed by hardware on ZC1
for example, in case of Mini Module GMM 5115: 1000 mA - 542 mA - 49 mA = 409 mA. For further information please refer to paragraph "ELECTRIC FEATURES".

INPUTS CONFIGURATION AS NPN OR PNP
ITALIAN TECHNOLOGY
The 16 optocoupled inputs of GMB HR168 can be configured as NPN or PNP according to the connection of jumpers J1 and J2. Power supply of optocoupling sections is provided externally through connector CN5 (please refer to paragraph "ELECTRIC FEATURES" and to paragraph of connector CN5 for further information); such power supply is rectified by a specific circuitery that generates two voltages: +Vopto and GND opto. Connection of jumper J1 and J2 determines which of these two voltages will be present at common pin of optocoupled inputs (pin 9 of CN1 and CN2, that is COM1 and COM2), while the other voltage will be present at all other pins of CN1 and CN2. This allows to close an optocoupled input simply by connecting it to its common pin. Jumpers J1 and J2 always must be moved together at the same time. They can be connected only both in position 1-2 or both in position 2-3. If one of the above rules is not respected, GMB HR168 could be damaged, so it is suggested to move jumpers J1 and J2 only when power supply is off. As already printed in table of figure 33, connecting J1 and J2 in position 1-2 configures inputs as type NPN, while connecting J1 and J2 in position 2-3 configures inputs as type PNP. About polarity of pins COM1 and COM2: as type NPN COM1 and COM2 are connected to +Vopto, while as type PNP COM1 and COM2 are connected to GND.
BACK UP GMB HR168 can be ordered with an optional Real Time Clock already installed (option .RTC). This component provides hours, minutes, seconds, dat, month and year and features a 256 bytes SRAM. On board is installed a Lithium battery to keep the time and the content of SRAM even when power supply is off, if jumper J9 is connected. By default, jumper J9 is NOT connected. For further information, please refer to paragraph "ELECTRIC FEATURES".
ANALOG INPUT GMB HR168 features an interface for one analog input that can accept an input voltage in a variable range according to connection of jumper J11: in position 1-2 the analog input signal is filtered, so that its stability is increased, while when J11 is in position 2-3, also a voltage divider acts on the signal, dividing its amplitude by 4. As shown in figure 24, such analog interface is based on high precision passive components that are selected during mounting phase to optimize signal acquisition. Anyway, to compensate eventual tollerances and thermal drifts, the best thing is to make a software calibration of the signal acquired, that is to calculate a correction coeffincent using a reference signal, then to use such coefficent for successive analog signal acquisitions. Examples developed for grifo(R) Mini Modules show some calibration techniques that the user can modify according to the application's needs. Please refer also to figure 4, if you are using a grifo(R) Mini Modules please refer to the combination manual. Page 40 GMB HR168 Rel. 5.00

SERIAL COMMUNICATION SELECTION
ITALIAN TECHNOLOGY
Serial line of GMB HR168 can be buffered in RS 232, RS 422, RS 485, Current Loop or TTL. By hardware can be selected which one of these electric standards is used, through jumpers connection (as described in the previous tables) and drivers installation. By software the serial line can be programmed to operate with all the standard physical protocols, in fact the bits per character, parity, stop bits and baud rates can be decided by installing the opportune hardware on socket ZC1. In the following paragraphs there are all the information on serial communication configurations. Some devices needed for RS 422, RS 485 and Current Loop configurations are not mounted on the board in standard configuration; this is why each fist non-standard (non-RS 232) serial configuration for line A must be always performed by grifo(R) technicians. This far the user can change in autonomy the configuration following the informations below: - HW SERIAL LINE IN RS 232 (default configuration) J3,J4 = not connected Hardware ZC1 J5 = indifferent IC10 J6 = position 2-3 IC11 J7 = position 2-3 IC12 J8 = position 2-3 IC8

Current Loop interface can be employed to make both point-to-point and multipoint connections through a 2-wires or a 4-wires connection.
- HW SERIAL LINE A IN RS 422 (option .RS 422) J3,J4 = (*) Hardware ZC1 J5 = position 2-3 (**) IC10 J6 = position 1-2 IC11 J7 = position 1-2 IC12 J8 = position 1-2 IC8

Status of signal DIR (software managed with Mini Module signal selected with J10), allows to enable or disable the transmitter: DIR = low level = logic state 0 -> transmitter enabled DIR =high level = logic state 1 -> transmitter disabled In point-to-point connections, signal DIR can be always kept low (trasnmitter always enabled), while in multi-point connections transmitter must be enabled only when a transmission is requested.

In this modality the signals to use are pins 5 and 6 of connector CN6, that become transmission or reception lines according to the status of signal DIR, managed by software, as follows: DIR DIR =low level =high level = logic state 0 = logic state 1 -> -> transmitter enabled transmitter disabled
This kind of serial communication can be used for multi-point connections, in addition it is possible to listen to own transmission, so the user is allowed to verify the succes of transmission. In fact, any conflict on the linecan be recognized by testing the received character after each transmission.

If using the RS 422 or RS 485 serial line, it is possible to connect the terminating and forcing circuit on the line by using jumpers J3 and J4. This circuit must be always connected in case of point-to-point connections, while in case of multi-point connections it must be connected olny in the farest boards, that is on the edges of the commmunication line. During a reset or a power on, signal DIR is at logic level high, so during these phases driver RS 485 is in reception or transmission driver RS 422 is disabled, to avoid confilcts on line.
(**) In case of RS 422 or RS 485 communication, signal DIR can be selected according to the connection of jumper J10: J10 in position 1-2 J10 in position 2-3 -> -> DIR = MM PIN 17 DIR = MM PIN 30
This allows to use the resources of hardware installed on socket ZC1 the best way possible, whithout having to use and I/O signal of CN4 for serial communication. (#) Serial line of hardware installed on socket ZC1 must be designed to connect signals MM PIN 9 and MM PIN 10 respectively to RS 232 RX and TX where "serial line in RS 232" is required or TTL RX and TX (e. g., generated by a microcontroller on board UART) where "serial line in TTL" is required

PERIPHERAL DEVICES SOFTWARE DESCRIPTION
In the previous paragraphs are described the external registers addresses, while in this one there is a specific description of registers meaning and function (please refer to I/O addresses table, for the registers names and addresses values). For a more detailed description of the devices, please refer to documentation of GMB HR168 + grifo(R) Mini Module combination. In the following paragraphs the D7/D0 and .0/7 indications denote the eight bits of the combination used in I/O operations.
RELAYS OUTPUTS Staus of 8 digital relays outputs is set through 8 signals of 40 pin socket ZC1. Please remark that signal driving relay OUT D2 can be connected either to signal MM PIN 16 or to signal MM PIN 30 according to the connection of jumper J10: J10 conncted in 3-4 J10 connected in 4-5 -> -> OUT D2 driven by MM PIN 30 OUT D2 driven by MM PIN 16
When the signal of socket ZC1 is set to logic state low (logic 0), the corresponding output is actived (relay contact is connected to its common pin), viceversa when the signal is set to logic state high (logic 1) the corresponding output is deactived (relay open). As previously said, LEDs LD1/8 provide a visual indication of digital outputs status (LED ON = output actived). Summarizing, the correspondance is: MM PIN 29 , OUT A1 -> MM PIN 28 , OUT A2 -> MM PIN 27 , OUT B1 -> MM PIN 26 , OUT B2 -> LED LD1 LED LD2 LED LD3 LED LD4 MM PIN 14 , OUT C1 -> MM PIN 15 , OUT C2 -> MM PIN 18 , OUT D1 -> (see above) , OUT D2 -> LED LD5 LED LD6 LED LD7 LED LD8
SERIAL LINE The signals used are the ones called TxD and RxD in figure 4, connected to signals MM PIN 9 and MM PIN 10 of 40 pins socket.

I2C BUS Signals used are pin 2 of CN8 (SDA) and pin 3 of CN8 (SCL) as shown in figure 4, connected respectively to signals MM PIN 12 and MM PIN 13 of socket ZC1. Signals SDA and SCL are also provided with 4.7 k pull up resistors. Slave address A0H is not usable by user if the optional Real Time Clock of GMB HR168 (option .RTC) is installed or is used a grifo(R) Mini Module provided with on board Real Time Clock.
OPTOCOUPLED INPUTS Status of 16 digital optocoupled inputs can be acquired by software by reading the status of corresponding singals of 40 pins socket, described in table of figure 4. When NPN or PNP inputs are enabled, corresponding signals are at logic state low (logic 0), viceversa when inputs are disabled a logic level high is acquired (logic 1). As previously said, LEDs LD9/24 give a visual indication of digital inputs status (LED ON means input actived). In detail, green LEDs (from LD9 to LD16), visualize optocoupled inputs from IN1-1 to IN8-1 of group 1 and referring to common pin COM1, while yellow LEDs (from LD17 to LD24), visualize optocoupled inputs from IN1-2 to IN8-2 of group 2 and referring to common pin COM2. Summarizing, the correspondance is: MM PIN 32 , IN1-1 MM PIN 31 , IN2-1 MM PIN 25 , IN3-1 MM PIN 24 , IN4-1 MM PIN 23 , IN5-1 MM PIN 22 , IN6-1 MM PIN 21 , IN7-1 MM PIN 19 , IN8-1 -> -> -> -> -> -> -> -> LED LD16 LED LD15 LED LD14 LED LD13 LED LD12 LED LD11 LED LD10 LED LD9 MM PIN 1 , IN1-2 MM PIN 2 , IN2-2 MM PIN 3 , IN3-2 MM PIN 4 , IN4-2 MM PIN 35 , IN5-2 MM PIN 36 , IN6-2 MM PIN 37 , IN7-2 MM PIN 38 , IN8-2 -> -> -> -> -> -> -> -> LED LD24 LED LD23 LED LD22 LED LD21 LED LD20 LED LD19 LED LD18 LED LD17
DIGITAL TTL I/O They are pins 2, 3, 4 and 6 of connector CN7, connected respectively to signals MM PIN 5, MM PIN 6, MM PIN 11 and MM PIN 30. Pin 8 of CN7 can also be used as digital I/O connected to signal MM PIN 33 (if J11 is connected in position 1-2), but remembering that it is always connected to a 4.7 k pull-down. In addition, pin 4 is connected to a yellow LED (LD28) that visualizes its status; in case an optional Real Time Clock is installed this signal is connected to its open collector output /INTRTC and cannot be used as user digital I/O.

RTC + SRAM
ITALIAN TECHNOLOGY
GMB HR168 can be ordered with an optional Real Time Clock + SRAM module already installed (option .RTC). The SRAM module, is provided with 256 bytes and the Real Time Clock which manages time (hours, minutes, seconds) and date (day, month, year, day of the week). Option is delivered with on board Lithium battery installed. RTC section can also generate periodic interrupts whose period can be programmed by the user, so it can be used to awaken CPU from low consumption working modes. For software management of serial SRAM+RTC module, please refer to specific documentation or to demo programs supplied with the card. The user must realize a serial communication with I2C bus standard protocol, through two ZC1 zoket signals. The only necessary information is the electric connection: DATA line (SDA) CLOCK line (SCL) -> -> MM PIN 12 P2.1 (input/output) MM PIN 13 P2.0 (output)
Please remark that A0 of this component's slave address is bound to logic 0, so its slave address is hexadecimal A0H. Logic state 0 of line corresponds to low level logic state (= 0 V), while logic state 1 correspons to high level logic state (= 5 V). We also would want to remark that SDA and SCL lines are connected to a 4.7 K pull-up resistor.
NOTE: When using a GMB HR168 provided with optional Real Time Clock, it is not possible to install a grifo(R) Mini Module with its own Real Time Clock on board, because they use the same slave address and would conflict.

7 FUNCTIONAL DESCRIPTION
PCF8583
Whenever an alarm event occurs the alarm flag of the control/status register is set. A timer alarm event will set the alarm flag and an overflow condition of the timer will set the timer flag. The open drain interrupt output is switched on (active LOW) when the alarm or timer flag is set (enabled). The flags remain set until directly reset by a write operation. When the alarm is disabled (Bit 2 of control/status register = 0) the alarm registers at addresses 08 to 0F may be used as free RAM. 7.3 Control/status register
The PCF8583 contains a 256 by 8-bit RAM with an 8-bit auto-increment address register, an on-chip 32.768 kHz oscillator circuit, a frequency divider, a serial two-line bidirectional I2C-bus interface and a power-on reset circuit. The first 16 bytes of the RAM (memory addresses 00 to 0F) are designed as addressable 8-bit parallel special function registers. The first register (memory address 00) is used as a control/status register. The memory addresses 01 to 07 are used as counters for the clock function. The memory addresses 08 to 0F may be programmed as alarm registers or used as free RAM locations, when the alarm is disabled. 7.1 Counter function modes
When the control/status register is programmed, a 32.768 kHz clock mode, a 50 Hz clock mode or an event-counter mode can be selected. In the clock modes the hundredths of a second, seconds, minutes, hours, date, month (four year calendar) and weekday are stored in a BCD format. The timer register stores up to 99 days. The event counter mode is used to count pulses applied to the oscillator input (OSCO left open-circuit). The event counter stores up to 6 digits of data. When one of the counters is read (memory locations 01 to 07), the contents of all counters are strobed into capture latches at the beginning of a read cycle. Therefore, faulty reading of the count during a carry condition is prevented. When a counter is written, other counters are not affected. 7.2 Alarm function modes
The control/status register is defined as the memory location 00 with free access for reading and writing via the I2C-bus. All functions and options are controlled by the contents of the control/status register (see Fig.3). 7.4 Counter registers
In the clock modes 24 h or 12 h format can be selected by setting the most significant bit of the hours counter register. The format of the hours counter is shown in Fig.5. The year and date are packed into memory location 05 (see Fig.6). The weekdays and months are packed into memory location 06 (see Fig.7). When reading these memory locations the year and weekdays are masked out when the mask flag of the control/status register is set. This allows the user to read the date and month count directly. In the event-counter mode events are stored in BCD format. D5 is the most significant and D0 the least significant digit. The divider is by-passed. In the different modes the counter registers are programmed and arranged as shown in Fig.4. Counter cycles are listed in Table 1.
By setting the alarm enable bit of the control/status register the alarm control register (address 08) is activated. By setting the alarm control register a dated alarm, a daily alarm, a weekday alarm or a timer alarm may be programmed. In the clock modes, the timer register (address 07) may be programmed to count hundredths of a second, seconds, minutes, hours or days. Days are counted when an alarm is not programmed.

When the alarm enable bit of the control/status register is set (address 00, bit 2) the alarm control register (address 08) is activated. All alarm, timer, and interrupt output functions are controlled by the contents of the alarm control register (see Fig.8). 7.6 Alarm registers
An alarm signal is generated when the contents of the alarm registers matches bit-by-bit the contents of the involved counter registers. The year and weekday bits are ignored in a dated alarm. A daily alarm ignores the month and date bits. When a weekday alarm is selected, the contents of the alarm weekday/month register will select the weekdays on which an alarm is activated (see Fig.9). Remark: In the 12 h mode, bits 6 and 7 of the alarm hours register must be the same as the hours counter.
Fig.6 Format of the year/date counter.
All alarm registers are allocated with a constant address offset of hexadecimal 08 to the corresponding counter registers (see Fig.4, Register arrangement).

The event counter stores up to 6 digits of data, which are stored as 6 hexadecimal values located in locations 1, 2, and 3. Thus, up to 1 million events may be recorded.

The timer (location 07) is enabled by setting the control/status register = XX0X X1XX. The timer counts up from 0 (or a programmed value) to 99. On overflow, the timer resets to 0. The timer flag (LSB of control/status register) is set on overflow of the timer. This flag must be reset by software. The inverted value of this flag can be transferred to the external interrupt by setting bit 3 of the alarm control register.
Fig.8 Alarm control register; clock mode.
Additionally, a timer alarm can be programmed by setting the timer alarm enable (bit 6 of the alarm control register). When the value of the timer equals a pre-programmed value in the alarm timer register (location 0F), the alarm flag is set (bit 1 of the control/status register). The inverted value of the alarm flag can be transferred to the external interrupt by enabling the alarm interrupt (bit 6 of the alarm control register). Resolution of the timer is programmed via the 3 LSBs of the alarm control register (see Fig.11, Alarm and timer Interrupt logic diagram). 7.8 Event counter mode Event counter mode is selected by bits 4 and 5 which are logic 1, 0 in the control/status register. The event counter mode is used to count pulses externally applied to the oscillator input (OSCO left open-circuit).
An event counter alarm occurs when the event counter registers match the value programmed in locations 9, A, and B, and the event alarm is enabled (bits 4 and 5 which are logic 0, 1 in the alarm control register). In this event, the alarm flag (bit 1 of the control/status register) is set. The inverted value of this flag can be transferred to the interrupt pin (pin 7) by setting the alarm interrupt enable in the alarm control register. In this mode, the timer (location 07) increments once for every one, one-hundred, ten thousand, or 1 million events, depending on the value programmed in bits 0, 1 and 2 of the alarm control register. In all other events, the timer functions are as in the clock mode. 7.9 Interrupt output The conditions for activating the open-drain n-channel interrupt output INT (active LOW) are determined by appropriate programming of the alarm control register. These conditions are clock alarm, timer alarm, timer overflow, and event counter alarm. An interrupt occurs when the alarm flag or the timer flag is set, and the corresponding interrupt is enabled. In all events, the interrupt is cleared only by software resetting of the flag which initiated the interrupt.

This allows the user to feed the 50 Hz reference frequency or an external high speed event signal into the input OSCI. 7.11 Initialization When power-up occurs the I2C-bus interface, the control/status register and all clock counters are reset. The device starts time-keeping in the 32.768 kHz clock mode with the 24 h format on the first of January at 0.00.00: 00. A 1 Hz square wave with 50% duty cycle appears at the interrupt output pin (starts HIGH). It is recommended to set the stop counting flag of the control/status register before loading the actual time into the counters. Loading of illegal states may lead to a temporary clock malfunction.

Fig.10 Alarm control register, event-counter mode.
In the clock mode, if the alarm enable is not activated (alarm enable bit of control/status register is logic 0), the interrupt output toggles at 1 Hz with a 50% duty cycle (may be used for calibration). This is the default power-on state of the device. The OFF voltage of the interrupt output may exceed the supply voltage, up to a maximum of 6.0 V. A logic diagram of the interrupt output is shown in Fig.11.

Oscillator and divider
A 32.768 kHz quartz crystal has to be connected to OSCI (pin 1) and OSCO (pin 2). A trimmer capacitor between OSCI and VDD is used for tuning the oscillator (see quartz frequency adjustment). A 100 Hz clock signal is derived from the quartz oscillator for the clock counters.
Page A-5
In the 50 Hz clock mode or event-counter mode the oscillator is disabled and the oscillator input is switched to a high impedance state.
