PCON Register
The Power Control (PCON) Register contains flag bits
to allow differentiation between a Power-on Reset
(POR), a Brown-out Reset (BOR), a Watchdog Reset
(WDT) and an external MCLR Reset.
REGISTER 2-8:
PCON REGISTER (ADDRESS: 8Eh)
Note:
BOR is unknown on POR. It must be set by
the user and checked on subsequent
RESETS to see if BOR is clear, indicating
a brown-out has occurred. The BOR status
bit is a don’t care and is not predictable if
the brown-out circuit is disabled (by clear-
ing the BODEN bit in the Configuration
Word).

bit 7-2
Unimplemented: Read as '0'
bit 1
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)
bit 0
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
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
