Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown

bit 6-1
bit 0
REGSLP: Voltage Regulator Low-Power Operation Enable bit⁽¹⁾
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⁽²⁾
1 = Watchdog Timer is on
0 = Watchdog Timer is off
Note 1: The REGSLP bit is automatically cleared when a Low-Voltage Detect condition occurs.
2: This bit has no effect if the Configuration bit, WDTEN, is enabled.
