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 Word 1

 01:

SBOREN is read/write, but has no effect on the BOR.

If BOREN <1:0> in Configuration Word 1 = 01:

1 = BOR Enabled

0 = BOR Disabled

bit 6-1

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
