Remark The clock supplied by the target system’s external clock (encircled in the figure) is used.
An external clock connected to the target system can be used via an emulation probe.
When the IE-789177-NS-EM1 is shipped, a 5.0 MHz crystal oscillator is already mounted in the IE-789177-NS-
EM1’s X1 UMCLK 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).
