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: 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 BOREN bit in the

Configuration word).

bit 1:

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)

bit 0:

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)
