The PCON register contains flag bits to differentiate
between a Power-on Reset (POR), an external MCLR
reset, WDT reset, Brown-out Reset (BOR), and Parity
Error Reset (PER). The PCON register also contains a
status bit, MPEEN, which reflects the value of the
MPEEN bit in Configuration Word. See Table 9-4 for
status of these bits on various resets.

Reflects the value of Configuration Word bit, MPEEN
PER: Memory Parity Error Reset Status bit
1 = No error occurred
0 = Program memory fetch parity error occurred
(must be set in software after a Parity Error Reset occurs)
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 Power-on Reset. It
must then be set by the user and checked
on subsequent resets to see if BOR is
cleared,
occurred. The BOR status bit is a “don't
care” and is not necessarily predictable if
the brown-out circuit is disabled (by
programming the BODEN bit in the
Configuration word).
