33.2.17 Deep Standby Cancel Source Select Register (DSSSR)
DSSSR is a 16-bit readable/writable register that consists of the bits for selecting a source to
cancel deep standby mode. The realtime clock alarm interrupt or change on the pins for canceling
(PC8 to PC5, PG11, PG10, PJ3, and PJ1) can be selected as a cancel source. The pins for
canceling can be used for canceling deep standby, regardless of pin function settings in the general
I/O port.
