(2) STOP mode release
(a) Release by unmasked interrupt request
The STOP mode can be released by the following two types of sources.
Standby release
When an unmasked interrupt request is generated, the STOP mode is released. 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.
Remark The broken line indicates the case when the interrupt request which has released the standby
signal
Clock
mode is acknowledged.
