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
q = Value depends on condition

SBOREN: Software Brown-out Reset Enable bit
If BOREN <1:0> in Configuration Words = 01:
1 = BOR Enabled
0 = BOR Disabled
If BOREN <1:0> in Configuration Words  00:
SBOREN is read/write, but has no effect on the BOR.
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.
Unimplemented: Read as ‘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 Configuration Words.
