bit 7
bit 0
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
bit 7
GPWUF: GPIO Reset bit
1
= Reset due to wake-up from Sleep on pin change
0
= After power-up or other Reset
bit 6
Reserved: Do not use. Use of this bit may affect upward compatibility with future products.
bit 5
Reserved: Do not use. Use of this bit may affect upward compatibility with future products.
bit 4
TO: Time-out bit
1
= After power-up, CLRWDT instruction or SLEEP instruction
0
= A WDT time-out occurred
bit 3
PD: Power-down bit
1
= After power-up or by the CLRWDT instruction
0
= By execution of the SLEEP instruction
bit 2
Z: Zero bit
1
= The result of an arithmetic or logic operation is zero
0
= The result of an arithmetic or logic operation is not zero
bit 1
DC: Digit carry/borrow bit (for ADDWF and SUBWF instructions)
ADDWF:
1
= A carry to the 4th low-order bit of the result occurred
0
= A carry to the 4th low-order bit of the result did not occur
SUBWF:
1
= A borrow from the 4th low-order bit of the result did not occur
0
= A borrow from the 4th low-order bit of the result occurred
bit 0
C: Carry/borrow bit (for ADDWF, SUBWF and RRF, RLF instructions)
ADDWF:
SUBWF:
RRF
or RLF:
1
= A carry occurred
1
= A borrow did not occur Load bit with LSb or MSb, respectively
0
= A carry did not occur
0
= A borrow occurred
