4.2.2.6 PCON REGISTER
The PCON register contains flag bits to differentiate
between a Power-on Reset, an external MCLR
reset,
WDT reset or a Brown-out Reset.
Note: BOD is unknown on Power-on Reset. It
must then be set by the user and checked
on subsequent resets to see if BOD
is
cleared, indicating a brown-out has
occurred. The BOD status bit is a "don't
care" and is not necessarily predictable if
the brown-out circuit is disabled (by
programming BODEN bit in the
configuration word).
