TABLE 8-1: SUMMARY OF REGISTERS ASSOCIATED WITH POWER-DOWN MODE

(1)

U-0 U-0 U-0 U-0 U-0 U-0 R/W-0/0 R/W-1/1

— — — — — —VREGPMReserved

bit 7 bit 0

Legend:

R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’

u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets

‘1’ = Bit is set ‘0’ = Bit is cleared

bit 7-2 Unimplemented: Read as ‘0’

bit 1 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

bit 0 Reserved: Read as ‘1’. Maintain this bit set.

Note 1: PIC16F1508/9 only.

2: See Section 29.0 “Electrical Specifications”.
