PIC16F688
2.2.2.6
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.

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
SBOREN: Software BOR Enable bit
1 = BOR enabled
0 = BOR disabled
