Table 3-4 shows the settings of the IE-789842-NS-EM1 when the system clocks in (1) to (3) are used.
Caution
Remark The factory settings of the IE-789842-NS-EM1 are those listed above under “when using clock that is
on emulation board
An external clock on the target system can be used via an emulation probe.
When the IE-789842-NS-EM1 is shipped, an 8.38 MHz crystal oscillator is already mounted in the IE-789842-
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’s clock source (this selects the emulator’s internal clock).

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’s 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) or the
oscillator is used.
