21.6.3 Securing oscillation stabilization time when releasing STOP mode
operation of the main clock oscillator stops after STOP mode is set.

Secure the oscillation stabilization time for the main clock oscillator after releasing the STOP mode because the

signal
Secure the oscillation stabilization time by setting the OSTS register.
When the releasing source is generated, the dedicated internal timer starts counting according to the OSTS
register setting. When it overflows, the normal operation mode is restored.
This operation is the same as that of a normal reset.
The oscillation stabilization time is the initial value of the OSTS register, 2
