(1) clock that is already mounted on emulation board (2) clock that is mounted by user (3) pulse input from target system (4) on-chip ring-osc if the target system includes a cl ock oscillator, select either (1) clock that is already mounted on emulation board, (2) clock that is mounted by user , or (4) on-chip ring-osc . for the clock oscillator, a resonator is connected to the target device and the target device?s internal oscillator is used. an example of the external circuit is shown in part (a) of figure 3-2. duri ng emulation, the oscillator that is m ounted on the target syst em is not used. instead, the clock that is mounted on t he emulation board installed in the ie- 78k0-ns or ie-78k0-ns-a is used. if the target system includes an ex ternal clock, select either (1) clock that is already mounted on emulation board , (2) clock that is mounted by user , (3) pulse input from target system , or (4) on-chip ring-osc . for the external clock, a clock signal is supplied from out side of the target device and t he target device?s internal oscillator is not used. an example of the external circuit is shown in part (b) of figure 3-2. caution the ie system will hang up if the main system clock is not supplied normally. moreover, be sure to input a rectangular w ave as the pulse from the target system. there is no need to supply a clock to the x2 pin. al so, even if a crystal resonator is connected directly to x1 (for the main system clock), the target device will not operate. figure 3-2. external circuits used as system clock oscillator (a) clock oscillator (b) external clock x1 crystal or ceramic resonator v ss external clock x2 x1 x2 target device target device chapter 3 installation user?s manual u16810ej1v0um 18 (1) clock that is already mounted on emulation board a 10.0 mhz crystal oscillator mounted on the IE-780862-NS-EM1 can be used. figure 3-3. when using clock that is already mounted on emulation board (main system clock) ie-78k0-ns or ie-78k0-ns-a emulation board mounted oscillator (used) emulation probe target system clock oscillator or external clock (not used) umclk remark the clock that is supplied by the oscillator of the IE-780862-NS-EM1 (encir cled in the figure) is used. (2) clock that is mounted by user the user can mount any clock support ed by the set specifications on the IE-780862-NS-EM1. this feature is effective when debugging at a different fr equency than the clock already mounted. remove the crystal oscillator (umclk) that is alr eady mounted on the emulation board, and mount the parts board on which the resonator to be used is mount ed or mount the oscillator to be used. figure 3-4. when using user-mount ed clock (main system clock) ie-78k0-ns or ie-78k0-ns-a emulation board parts board + oscillator or oscillator (used) emulation probe target system clock oscillator or external clock (not used) umclk remark the clock that is supplied by t he resonator of the IE-780862-NS-EM1 (encircled in the figure) or the oscillator is used. chapter 3 installation user?s manual u16810ej1v0um 19 (3) pulse input from target system an external clock on the target syst em can be used via an emulation probe. figure 3-5. when supplying pulse from target system ie-78k0-ns or ie-78k0-ns-a emulation board emulation probe target system external clock (used) mounted oscillator (not used) umclk remark the pulse that is supplied by the external clock on the target system (encircled in the figure) is used. (4) on-chip ring-osc the ring-osc on the emul ation board can be used. (a) when using high-speed ring-osc the high-speed ring-osc on the emulation board can be used. figure 3-6. when using high-speed ring-osc ie-78k0-ns or ie-78k0-ns-a emulation board high-speed ring-osc on emulation board is used emulation probe target system clock oscillator or external clock (not used) chapter 3 installation user?s manual u16810ej1v0um 20 (b) when using low-speed ring-osc the low-speed ring-osc on the emulation board can be used. figure 3-7. when using low-speed ring-osc ie-78k0-ns or ie-78k0-ns-a emulation board low-speed ring-osc on emulation board is used emulation probe target system clock oscillator or external clock (not used) 3.2.2 main system clock settings table 3-1 shows the settings of t he IE-780862-NS-EM1 when the main system clocks in (1) to (4) are used. table 3-1. main system clock settings frequency of main system clock mask options (systemclock) sfr (mcm0) IE-780862-NS-EM1 umclk cpu clock source selection note 2 (id78k0-ns) (1) when using clock that is already mounted on emulation board 10.0 mhz oscillator (2) when using clock mounted by user oscillator assembled or prepared by user internal (3) when inputting pulse from target system other than 10.0 mhz x1orrc external high-speed ring-osc 8.0 mhz highspeedring 1 (4) when using on- chip ring-osc low-speed ring-osc note 1 240 khz x1orrc or highspeedring 0 oscillator (not used) internal or external notes 1. the IE-780862-NS-EM1 oper ates with the low-speed ring-osc clock when the integrated debugger is activated and immediately after reset. 2. select the source clock for the main system clock when the integrated debugger is started. after that, do not change the setting. remark sfr mcm0 is set to 0 under the factory setting of the IE-780862-NS-EM1. chapter 3 installation user?s manual u16810ej1v0um 21 (1) when using clock that is already mounted on emulation board when the IE-780862-NS-EM1 is shipped, a 10.0 mhz crystal oscillator is already mounted in the ie-780862-ns- em1?s socket (umclk). when using the factory-set m ode settings, there is no need to make any other hardware settings. when starting the integrated debugger (id78k0-ns), open the c onfiguration dialog box and se lect ?internal? in the area (clock) for selecting the cpu?s clock source (this selects the emulator?s internal clock). after the debugger is activated, if ?x1orrc? is selected for the mask opt ion systemclock in the mask option dialog box and the sfr mcm0 is changed to 1, the cpu operating clock is switched from the low-speed ring- osc to the clock already m ounted on the emulation board. (2) when using clock mounted by user perform the settings described under either (a) or (b), depending on the type of clock to be used. when starting the integrated debugger (id78k0-ns), open the c onfiguration dialog box and se lect ?internal? in the area (clock) for selecting the cpu?s clock source (this selects the emulator?s internal clock). after the debugger is activated, if ?x1orrc? is selected for the mask opt ion systemclock in the mask option dialog box and the sfr mcm0 is changed to 1, the cpu operating clock is switched from the low-speed ring- osc to the clock mounted by user.

(4) when using on-chip ring-osc (a) when using high-speed ring-osc no hardware settings are required for this situation. after the integrat ed debugger (id78k0-ns) is activated, if ?highspeedring? is selected for the mask option systemclock in the mask option dialog box and the sfr mcm0 is changed to 1, the cpu operating clock is s witched from the low-speed ring-osc to the high-speed ring-osc on the emulation board.
