2.2.2.6
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.
These devices contain an additional bit to differentiate
a Brown-out Reset condition from a Power-on Reset
condition.

bit 7
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)
Legend:
R = Readable bit
-n = Value at POR

Note:
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
If the BOREN configuration bit is clear,
BOR is unknown on Power-on Reset.
If the BOREN configuration bit is set, BOR
is ‘1’ on Power-on Reset and reset to ‘0’
when a Brown-out condition occurs. BOR
must then be set by the user and checked
on subsequent resets to see if it is clear,
indicating that another Brown-out has
occurred.
