PCON Register
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 2-8:
Note:
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 not predictable if the brown-out circuit
is disabled (by clearing the BOREN bit in
the Configuration Word).
