Releasing STOP mode
The STOP mode can be released by the following two types of sources:
(a) Releasing by unmasked interrupt request
The STOP mode can be released by an unmasked interrupt request. In this case, if the interrupt is
enabled to be accepted, vectored interrupt processing is performed, after the oscillation settling time
has elapsed. If the interrupt acceptance is disabled, the instruction at the next address is executed.
