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.

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  
bit 7-6  
bit 5  
Unimplemented: Read as ‘0’  
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)  
1= BOR enabled  
0= BOR disabled  
bit 3-2  
bit 1  
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)  
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> = 01in the Configuration Word register for this bit to control the BOR.
