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.

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

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

the

Configuration word).

bit 7

bit 0

bit 7-4

Unimplemented: Read as '0'

bit 3

OSCF: INTRC/ER oscillator frequency

= 4 MHz typical(1)

= 37 KHz typical

bit 2

Unimplemented: Read as '0'

bit 1

POR: Power-on Reset STATUS bit

= 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

= No Brown-out Reset occurred

= 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

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

’1’ = Bit is set

’0’ = Bit is cleared

x = Bit is unknown
