IPEN: Interrupt Priority Enable bit
1 = Enable priority levels on interrupts
0 = Disable priority levels on interrupts (PIC16CXXX Compatibility mode)
bit 6
SBOREN: BOR Software Enable bit(1)
If BOREN1:BOREN0 = 01:
1 = BOR is enabled
0 = BOR is disabled
If BOREN1:BOREN0 = 00, 10 or 11:
Bit is disabled and read as 鈥�0鈥�.
bit 5
Unimplemented: Read as 鈥�0鈥�
bit 4
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
a Brown-out Reset occurs)
bit 3
TO: Watchdog Time-out Flag bit
1 = Set by power-up, CLRWDT instruction or SLEEP instruction
0 = A WDT time-out occurred
bit 2
PD: Power-down Detection Flag bit
1 = Set by power-up or by the CLRWDT instruction
0 = Set by execution of the SLEEP instruction
bit 1
POR: Power-on Reset Status bit(2)
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)
bit 0
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)
Note 1: The SBOREN bit is only available when the BOREN1:BOREN0 Configuration
bits = 01; otherwise, it is disabled and reads as 鈥�0鈥�. See Section 4.4 鈥淏rown-out
2: The actual Reset value of POR is determined by the type of device Reset. See the
notes following this register and Section 4.6 鈥淩eset State of Registers鈥� for
additional information.
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as 鈥�0鈥�
-n = Value at POR
鈥�1鈥� = Bit is set
鈥�0鈥� = Bit is cleared
x = Bit is unknown
Note 1: 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.
2: Brown-out Reset is said to have occurred when BOR is 鈥�0鈥� and POR is 鈥�1鈥� (assuming
that POR was set to 鈥�1鈥� by software immediately after POR).
