Stop Mode Release By Interrupt Generation - NEC PD78081(A) User Manual

(2) STOP mode release
The STOP mode can be cleared with the following two types of sources.
(a) Release by unmasked interrupt request
An unmasked interrupt request is used to release the STOP mode. If interrupt acknowledge is enabled
after the lapse of oscillation stabilization time, vectored interrupt service is carried out. If interrupt
acknowledge is disabled, the next address instruction is executed.
