Includes oscillator circuit
When using external
clock
Other than 8.0000 MHz
Shortcut 6-8
External
Caution:When using an user defined clock or external clock, open the configuration dialog 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-78K0-NS-P04 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-78K0-NS-P04 is shipped, an 8.0000-MHz crystal resonator is already mounted in the
IE-78K0-NS-P04 X4 socket. When using the factory-set mode settings, there is no need to make
any other hardware settings.
When starting the integrated debugger (ID78K0-NS), open the configuration dialog and select
“Internal” in the area (Clock) for selecting the CPU’s clock source (this selects the emulator’s internal
clock).
