The REGSLP bit is automatically cleared when a Low-Voltage Detect condition occurs.
This bit has no effect if the Configuration bit, WDTEN, is enabled.
REGSLP
REGSLP: Voltage Regulator Low-Power Operation Enable bit
1 = On-chip regulator enters low-power operation when device enters Sleep mode
0 = On-chip regulator continues to operate normally in Sleep mode
Unimplemented: Read as ‘0’
SWDTEN: Software Controlled Watchdog Timer Enable bit
1 = Watchdog Timer is on
0 = Watchdog Timer is off
