(3) When inputting pulse from target system
(4) When using Ring-OSC

No hardware settings are required for this situation.
When starting the integrated debugger (ID78K0-NS), open the configuration dialog box and select “External” in
the area (Clock) for selecting the CPU’s clock source (this selects the user’s clock).
After the integrated debugger is started, if “X1orRC” is selected for the mask option SystemClock in the Mask
Option dialog box and the SFR register MCM0 is changed to 1, the CPU operating clock is switched from Ring-
OSC to the external clock.
Ring-OSC (240 kHz) is selected as the CPU operating clock when the IE system is activated.
See 3.2.2 (1) to (4) when changing the setting.
Caution
The above steps configure the following circuit and enable supply of the clock from the mounted resonator to
the emulation device.

Use of the peripheral functions, except for the following cases, is prohibited when Ring-OSC
is selected as the CPU operating clock (MCM0 = 0).
• When watchdog timer is used
• When clock monitor is used
• TMH1 (When fosc/2
• When peripheral function that uses an external clock as the operating clock is used
