PIC16F882/883/884/886/887
2.2.2.8
The Power Control (PCON) register (see Register 2-8)
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.
