by software” is set, oscillation can be controlled by the internal oscillation mode register (RCM).
5.4.5
Internal high-speed oscillator is incorporated in the PD78F0711 and 78F0712. Oscillation can be controlled by
When the internal high-speed oscillation clock is selected as the high-speed system clock by using the option byte,
Internal low-speed oscillator is incorporated in the PD78F0711 and 78F0712. Oscillation can be controlled by the
The internal low-speed oscillation clock is used as the clock of the CPU, the watchdog timer, and 8-bit timer H1.
“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 (240 kHz (TYP.))
The prescaler generates various clocks to be supplied to the CPU by dividing the main system clock.
