2.2.2.8
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.

bit 1
bit 0
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 dis-
abled (by clearing the BOREN bit in the
configuration word).

bit 7
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)
