2.2.2.3 PCON Register
The Power Control (PCON) register contains flag bits
(refer to Table 3-4) 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.

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 Power-on Reset or Brown-out Reset
occurs)
