(3) Pulse input from target system
3.5.2 Main system clock settings
(1) When using clock that is already mounted on emulation board
(1) When using clock that is already mounted
(2) When using clock mounted by user
(3) When inputting pulse from target system
Table 3-4 shows the settings of the IE-789468-NS-EM1 when the main system clocks in (1) to (3) are used.
Caution
Remark
on emulation board
An external clock on the target system can be used as both the main system clock and subsystem clock via an
emulation probe.
When the IE-789468-NS-EM1 is shipped, a 5.0 MHz crystal oscillator is already mounted in the IE-789468-NS-
EM1’s X1 socket. When using the factory-set mode settings, there is no need to make any other hardware
settings.
When starting the integrated debugger (ID78K0S-NS), open the configuration dialog box and select “Internal” in
the area (Clock) for selecting the CPU clock source (this selects the emulator’s internal clock).

Emulation board
The factory settings of the IE-789468-NS-EM1 are those listed above under “when using clock that is
already mounted on emulation board”.
When inputting a pulse from the target system, open the configuration dialog box when starting
the integrated debugger (ID78K0S-NS) and select “External” in the area (Clock) for selecting the
CPU clock source (this selects the user’s clock).
The pulse that is supplied by the external clock on the target system (encircled in the figure) is used.
