2.2.2.6
The Power Control (PCON) register (see Table 12-3)
contains flag bits to differentiate between a:
• Power-on Reset (POR)
• Wake-up Reset (WUR)
• 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.
The PCON register bits are shown in Register 2-6.
