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: 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
cleared, 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
programming
BODEN
bit
in
the
Configuration word).
