Frequency of System Clock

Parts Board (X1)

CPU Clock Source

Selection (ID)

When using clock that is

already mounted on

emulation board

6 MHz

Oscillator used

When using clock mounted

by user

Oscillator assembled by user

Internal

When pulse is input from

target system

Other than 6 MHz

Oscillator not used

External

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).
