Only 0 can be written to this bit.
RSTSR indicates a source for generating an internal reset.
DPSRSTF Flag (Deep Software Standby Reset Flag)
The DPSRSTF flag indicates that deep software standby mode is canceled by an external interrupt source specified with
the deep standby interrupt enable register (DPSIER) or the deep standby interrupt flag register (DPSIFR) and an internal
reset is generated.
The DPSRSTF flag is initialized by the reset signal from the RES# pin, but is not initialized by the internal reset signal
that is used to cancel deep software standby mode.
[Setting condition]
•
When deep software standby mode is canceled by an external interrupt source
[Clearing condition]
•
When this bit is read as 1 and then written by 0
