If it is not necessary to use the subsystem clock for low power consumption operations, or if not using the
Remark OSCSELS:
The internal high-speed oscillator is incorporated in the 78K0/LC3. Oscillation can be controlled by the internal
After a reset release, the internal high-speed oscillator automatically starts oscillation (8 MHz (TYP.)).
The internal low-speed oscillator is incorporated in the 78K0/LC3.
The internal low-speed oscillation clock is only used as the clock of the watchdog timer, 8-bit timer H1, and LCD
“Can be stopped by software” or “Cannot be stopped” can be selected by the option byte. When “Can be stopped
After a reset release, the internal low-speed oscillator automatically starts oscillation, and the watchdog timer is
