The Power Control (PCON) Register contains flag bits
to allow differentiation between a Power-on Reset
(POR), a Brown-out Reset (BOR), a Watch-dog Reset
(WDT) and an external MCLR Reset.

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)

BOR is unknown on POR. It must be set by
the user and checked on subsequent rests
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 clearing
the BODEN bit in the configuration word).
