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 Enabled

0 = BOR 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.

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 Configuration Words.
