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).
