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 Watchdog Reset
(WDT) and an external MCLR Reset.
REGISTER 4-8:

bit 7-2
bit 1
bit 0
PCON Register
PCON REGISTER (ADDRESS 8Eh)
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)
bit 7
Legend:
R = Readable bit
-n = Value at POR

Note:
U = Unimplemented bit, read as ‘0’
’0’ = Bit is cleared
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).
