5.6.4 Example of controlling internal low-speed oscillation clock
driven (30 kHz (TYP.)) if the watchdog timer operation has been enabled by the option byte.
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

Internal low-speed oscillator can be stopped by software
<1> Setting LSRSTOP to 1 (RCM register)
<1> Clearing LSRSTOP to 0 (RCM register)
When LSRSTOP is set to 1, the internal low-speed oscillation clock is stopped.
When LSRSTOP is cleared to 0, the internal low-speed oscillation clock is restarted.
the internal low-speed oscillation clock cannot be controlled.
