supported by the µPD780828B(A) series.
Caution:When using an an user defined clock or external clock, open the configuration dialog
Remark: The IE-78K0-NS-P04 factory settings are those listed above under “when using clock that is
(1) When using clock that is already mounted on emulation board
The IE-78K0-NS-P04 supports the using of a subclock for the emulation. But this function is not
An external clock connected to the target system can be used via the emulation probe.
3.2.3 Subsystem Clock
3.2.4 Main system clock settings
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).
