5.6.4 Example of controlling internal low-speed oscillation clock
driven (240 kHz (TYP.)) if the watchdog timer operation has been enabled by the option byte.
5.6.5 Clocks supplied to CPU and peripheral hardware
of registers.
The internal low-speed oscillation clock cannot be used as the CPU clock.
Only the following peripheral hardware can operate with this clock.
In addition, the following operation modes can be selected by the option byte.
The internal low-speed oscillator automatically starts oscillation after a reset release, and the watchdog timer is
(1) Example of setting procedure when stopping the internal low-speed oscillation clock
(2) Example of setting procedure when restarting oscillation of the internal low-speed oscillation clock
Caution If “Internal low-speed oscillator cannot be stopped” is selected by the option byte, oscillation of
