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 Detect.
REGISTER 3-6:
PCON REGISTER (ADDRESS: 0Ch)
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
clearing
the
BODEN
Configuration word).

POR
: Power-on Reset STATUS bit
1
= No Power-on Reset occurred

= A Power-on Reset occurred (must be set in software after a Power-on Reset occurs)
bit 0
BOD
: Brown-out Detect 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)
Note 1:
When in ER Oscillator mode, setting OSCF = 1 will cause the oscillator frequency to
change to the frequency specified by the external resistor.
