The Power Control (PCON) register contains flag bits
to differentiate between a:
• Power-on Reset (POR)
• Brown-out Reset (BOR)
• Reset Instruction Reset (RI)
• MCLR Reset (RMCLR)
• Watchdog Timer Reset (RWDT)
• Stack Underflow Reset (STKUNF)
• Stack Overflow Reset (STKOVF)
The PCON register bits are shown in
