2.2.2.3 PCON Register
The Power Control (PCON) register contains flag bits
(refer to Table 3-2) 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 software enable of
the BOR.
The PCON register bits are shown in Register 2-3.

bit 7 bit 0
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
q = Value depends on condition
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 Power-on Reset or Brown-out Reset
occurs)
Note 1: Set BOREN<1:0> = 01 in the Configuration Word register for this bit to control the BOR.
