4.2.2.8
The Power Control (PCON) register contains flag bits to
allow differentiation between a Power-on Reset (POR),
a Brown-out Reset (BOR), a Watch-dog Reset (WDT)
and an external MCLR Reset.

PCON REGISTER
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
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).
BOR
R = Readable bit
W = Writable bit
U = Unimplemented bit,
-n = Value at POR reset
