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

STKOVF: Stack Overflow Flag bit
1 = A Stack Overflow occurred
0 = A Stack Overflow has not occurred or set to ‘0’ by firmware
STKUNF: Stack Underflow Flag bit
1 = A Stack Underflow occurred
0 = A Stack Underflow has not occurred or set to ‘0’ by firmware
Unimplemented: Read as ‘0’
RMCLR: MCLR Reset Flag bit
1 = A MCLR Reset has not occurred or set to ‘1’ by firmware
0 = A MCLR Reset has occurred (set to ‘0’ in hardware when a MCLR Reset occurs)
RI: RESET Instruction Flag bit
1 = A RESET instruction has not been executed or set to ‘1’ by firmware
0 = A RESET instruction has been executed (set to ‘0’ in hardware upon executing a RESET instruction)
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
