Note
Caution The above-mentioned oscillation accuracy stabilization wait time will be stated after the device
The STOP mode can be released by the following two sources.
(a) Release by unmasked interrupt request
When an unmasked interrupt request is generated, the STOP mode is released.
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.
The wait time is as follows:
