4.2.2.8 PCON Register

The Power Control (PCON) register contains flag bits

to allow differentiation between a Power-on Reset

(POR), a Brown-out Reset (BOR), a Watchdog Reset

(WDT) and an external MCLR Reset.

Note:

BOR is unknown on POR. It must be set by

the user and checked on subsequent

RESETS to see if BOR is clear, indicating

a brown-out has occurred. The BOR status

bit is a “don't care” and is not predictable if

the brown-out circuit is disabled (by clear-

ing the BODEN bit in the configuration

word).

Unimplemented: Read as '0'

POR: Power-on Reset Status bit

1 = No Power-on Reset occurred

0 = A Power-on Reset occurred (must be set in software after a Power-on Reset occurs)

BOR: Brown-out Reset Status bit

1 = No Brown-out Reset occurred

0 = A Brown-out Reset occurred (must be set in software after a Brown-out Reset occurs)

Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

’1’ = Bit is set

U = Unimplemented bit, read as ‘0’

’0’ = Bit is cleared x = Bit is unknown
