23.6.4 Securing oscillation stabilization time when releasing STOP mode
operation of the main clock oscillator stops after STOP mode is set.
Oscillation waveform
Secure the oscillation stabilization time for the main clock oscillator after releasing the STOP mode because the
(1) Releasing STOP mode by non-maskable interrupt request signal or unmasked maskable interrupt
(2) Release by reset
Interrupt request
request 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 differs depending on the option byte. For details, see CHAPTER 29 OPTION
BYTE.
