(a) Release by unmasked interrupt request
When an unmasked interrupt request is generated, the STOP mode is released. After the oscillation stabilization
time has elapsed, if interrupt acknowledgment is enabled, vectored interrupt servicing is carried out. If interrupt
acknowledgment is disabled, the next address instruction is executed.
Standby release signal
Remark The broken lines indicate the case when the interrupt request that has released the standby mode is
