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.

If SBOREN is enabled, its Reset state is ‘1’; otherwise, it is ‘0’. See Register 4-1 for additional information.
The actual Reset value of POR is determined by the type of 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: BOR Software 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 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.
