6.3 Register Definitions: BOR Control
REGISTER 6-1: BORCON: BROWN-OUT RESET CONTROL REGISTER
R/W-1/u R/W-0/u U-0 U-0 U-0 U-0 U-0 R-q/u
SBOREN BORFS
(1)
— — — — — BORRDY
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 q = Value depends on condition
bit 7 SBOREN: Software Brown-out Reset Enable bit
If BOREN<1:0> in Configuration Words =
01:
1 = BOR is enabled
0 = BOR is disabled
If BOREN <1:0> in Configuration Words
 01:
SBOREN is read/write, but has no effect on the BOR.
bit 6 BORFS: Brown-out Reset Fast Start bit
(1)
If BOREN <1:0> = 10 (Disabled in Sleep) or BOREN<1:0> = 01 (Under software control):
1 = Band gap is forced on always (covers Sleep/wake-up/operating cases)
0 = Band gap operates normally and may turn off
If BOREN<1:0> =
11 (Always On) or BOREN<1:0> = 00 (Always Off):
BORFS is read/write, but has no effect on the BOR.
bit 5-1 Unimplemented: Read as ‘0’
bit 0 BORRDY: Brown-out Reset Circuit Ready Status bit
1 = The Brown-out Reset circuit is active
0 = The Brown-out Reset circuit is inactive
Note 1: BOREN<1:0> bits are located in the Configuration Words.
