RCON: RESET CONTROL REGISTER
bit 7
IPEN: Interrupt Priority Enable bit
1 = Enable priority levels on interrupts
0 = Disable priority levels on interrupts (PIC16CXXX Compatibility mode)
Unimplemented: Read as ‘0’
RI: RESET Instruction Flag bit
1 = The RESET instruction was not executed (set by firmware only)
0 = The RESET instruction was executed causing a device Reset (must be set in software after
TO: Watchdog Time-out Flag bit
1 = Set by power-up, CLRWDT instruction or SLEEP instruction
0 = A WDT time-out occurred
PD: Power-Down Detection Flag bit
1 = Set by power-up or by the CLRWDT instruction
0 = Set by execution of the SLEEP instruction
POR: Power-on Reset Status bit
1 = A Power-on Reset has not occurred (set by firmware only)
0 = A Power-on Reset occurred (must be set in software after a Power-on Reset occurs)
BOR: Brown-out Reset Status bit
1 = A Brown-out Reset has not occurred (set by firmware only)
0 = A Brown-out Reset occurred (must be set in software after a Brown-out Reset occurs)
Legend:
R = Readable bit
-n = Value at POR
R/W-0
Note:
IPEN
Note 1: It is recommended that the POR bit be set after a Power-on Reset has been
a Brown-out Reset occurs)
2: If the on-chip voltage regulator is disabled, BOR remains ‘0’ at all times. See
3: Brown-out Reset is said to have occurred when BOR is ‘0’ and POR is ‘1’
BOR is not available in PIC18LF2XJ10/4XJ10 devices.
