Caution
When a pulse is input from 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).
Remark
The IE-789801-NS-EM1’s factory settings are those listed above under “when using clock that is already
mounted on emulation board”.
(1) When using clock that is already mounted on emulation board
When the IE-789801-NS-EM1 is shipped, a 6 MHz crystal oscillator is already mounted in the IE-789801-NS-
EM1’s X1 socket. If the IE-789801-NS-EM1 is in the same state as when shipped, no hardware settings are
required.
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).
