Caution The above-mentioned oscillation accuracy stabilization wait time will be stated after the
Remark The broken lines indicate the case when the interrupt request that has released the standby mode
When the reset signal is generated, STOP mode is released, and then, as in the case with a normal reset
operation, the program is executed after branching to the reset vector address.
