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 BODEN bit in the

Configuration word).

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)

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)

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
