Legend:
R = Readable bit
u = Bit is unchanged
‘1’ = Bit is set
W = Writable bit
x = Bit is unknown
‘0’ = Bit is cleared
U = Unimplemented bit, read as ‘0’
-n/n = Value at POR and BOR/Value at all other Resets

bit 1
bit 0
Note 1:
2:
Unimplemented: Read as ‘0’
VREGPM: Voltage Regulator Power Mode Selection bit
1 = Low-Power Sleep mode enabled in Sleep⁽²⁾
Draws lowest current in Sleep, slower wake-up
0 = Normal Power mode enabled in Sleep⁽²⁾
Draws higher current in Sleep, faster wake-up
Reserved: Read as ‘1’. Maintain this bit set.
PIC16F1526/27 only.
