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

PCON REGISTER
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)
Reserved
This bit should be set upon a Power-on Reset by user software and maintained as set. Use of this bit as a general
purpose read/write bit is not recommended, since this may affect upward compatibility with future products.
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)

Note:
POR
POR
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).
