The RCON register contains flag bits which are used to
determine the cause of the last Reset or wake-up from
Idle or Sleep modes. RCON also contains the IPEN bit
which enables interrupt priorities.

RCON Register
Actual Reset values are determined by device configuration and the nature of the device Reset. See
Register 4-1 for additional information.
IPEN: Interrupt Priority Enable bit
1 = Enable priority levels on interrupts
0 = Disable priority levels on interrupts (PIC16CXXX Compatibility mode)
SBOREN: Software BOR Enable bit
For details of bit operation, see Register 4-1.
Unimplemented: Read as ‘0’
RI: RESET Instruction Flag bit
For details of bit operation, see Register 4-1.
TO: Watchdog Timer Time-out Flag bit
For details of bit operation, see Register 4-1.
PD: Power-Down Detection Flag bit
For details of bit operation, see Register 4-1.
POR: Power-on Reset Status bit
For details of bit operation, see Register 4-1.
BOR: Brown-out Reset Status bit
For details of bit operation, see Register 4-1.
