PCON Register

The Power Control (PCON) register (see Register 2-6)
contains flag bits to differentiate between a:
• Power-on Reset (POR)
• Brown-out Reset (BOR)
• Watchdog Timer Reset (WDT)
• External MCLR Reset
The PCON register also controls the Ultra Low-Power
Wake-up and software enable of the BOR.

bit 7
Legend:
R = Readable bit
W = Writable bit
-n = Value at POR
‘1’ = Bit is set
bit 7-6
Unimplemented: Read as ‘0’
bit 5
ULPWUE: Ultra Low-Power Wake-up Enable bit
1 = Ultra low-power wake-up enabled
0 = Ultra low-power wake-up disabled
bit 4
SBOREN: Software BOR Enable bit
1 = BOR enabled
0 = BOR disabled
bit 3-2
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)
Note 1:
BOREN<1:0> = 01 in the Configuration Word register for this bit to control the BOR.
