(3) External clock
An external clock connected to the target system can be used via an emulation probe.
Note that 6 to 8 are shorted on the parts board.
IE-78K0-NS
IE-178098-NS-EM1
Remark
The clock supplied by the target system's clock generator (encircled in the figure) is used.

Caution When using an external clock, open the configuration dialog box when starting the integrated
debugger (ID78K0-NS) and select "External" in the area (Clock) for selecting the CPU's clock
source (this selects the user's clock).
Remark
The IE-178098-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-178098-NS-EM1 is shipped, a 6.3 MHz crystal resonator (X1) is already mounted on the IE-178098-
NS-EM1. When using the factory-set mode settings (6 to 8 are shorted on the parts board), there is no need to
make any other hardware settings.
When starting the integrated debugger (ID78K0-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).
