RCON Register
The Reset Control (RCON) register contains flag bits
that allow differentiation between the sources of a
device Reset. These flags include the TO, PD, POR,
BOR and RI bits. This register is readable and writable.
REGISTER 4-3:
RCON: RESET CONTROL REGISTER
Note 1: If the BOREN configuration bit is set,
BOR is ‘1’ on Power-on Reset. If the
BOREN configuration bit is clear, BOR is
unknown on Power-on Reset.
The BOR status bit is a “don’t care” and is
not necessarily predictable if the brown-
out circuit is disabled (the BOREN config-
uration bit is clear). BOR must then be set
by the user and checked on subsequent
Resets to see if it is clear, indicating a
brown-out has occurred.
2: It is recommended that the POR bit be set
after
a
Power-on
Reset
has
been
detected, so that subsequent Power-on
Resets may be detected.

IPEN: Interrupt Priority Enable bit
1
= Enable priority levels on interrupts
0
= Disable priority levels on interrupts (PIC16CXXX Compatibility mode)
bit 6-5
Unimplemented: Read as ‘0’
bit 4
RI: RESET Instruction Flag bit
1
= The RESET instruction was not executed
0
= The RESET instruction was executed causing a device Reset
(must be set in software after a Brown-out Reset occurs)
bit 3
TO: Watchdog Time-out Flag bit
1
= After power-up, CLRWDT instruction or SLEEP instruction
0
= A WDT time-out occurred
bit 2
PD: Power-down Detection Flag bit
1
= After power-up or by the CLRWDT instruction
0
= By execution of the SLEEP instruction
bit 1
POR: Power-on Reset Status bit
1
= A Power-on Reset has not occurred
0
= A Power-on Reset occurred (must be set in software after a Power-on Reset occurs)
bit 0
BOR: Brown-out Reset Status bit
1
= A Brown-out Reset has not occurred
0
= A Brown-out Reset occurred (must be set in software after a Brown-out Reset occurs)
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
