(2) When using clock mounted by user
(3) When inputting pulse from target system
Table 3-1 shows the settings of the IE-780354-NS-EM1 when the main system clocks in (1) to (3) are used.
Caution
Remark The factory settings of the IE-780354-NS-EM1 are those listed above under “when using clock that is
on emulation board
An external clock on the target system can be used as both the main system clock and subsystem clock via an
emulation probe.
When the IE-780354-NS-EM1 is shipped, a 10.0 MHz crystal oscillator is already mounted in the IE-780354-NS-
EM1’s socket (UMCLK).

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).

When inputting a pulse from the target system, 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).
The pulse that is supplied by the external clock on the target system (encircled in the figure) or the
oscillator is used.
