4.2.2.8
The Power Control (PCON) register contains a flag bit
to allow differentiation between a Power-on Reset
(POR) to an external MCLR Reset or WDT Reset.
Those devices with brown-out detection circuitry con-
tain an additional bit to differentiate a Brown-out Reset
condition from a Power-on Reset condition.

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
1 = No Brown-out Reset occurred

Note:
BOR
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
clear, indicating a brown-out has occurred.
The BOR status bit is a don't care and is
not necessarily predictable if the brown-out
circuit is disabled (by clearing the BODEN
bit in the Configuration word).
