3.2.2.6 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 Detect.

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 bit in the

Configuration word).

Unimplemented: Read as '0'

OSCF: INTRC/ER oscillator frequency

1 = 4 MHz typical(1)

0 = 37 KHz typical

Unimplemented: Read as '0'

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)

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.

Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

’1’ = Bit is set

U = Unimplemented bit, read as ‘0’

’0’ = Bit is cleared x = Bit is unknown
