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

brown-out

has

occurred. The BOR status bit is a "don't

care" and is not necessarily predictable if

the

brown-out

circuit

disabled

(by

programming

BOREN

bit

the

Conﬁguration word).
