PIC18F6390/6490/8390/8490
5.3.5
The Status register, shown in Register 5-2, contains the
arithmetic status of the ALU. As with any other SFR, it
can be the operand for any instruction.
If the Status register is the destination for an instruction
that affects the Z, DC, C, OV or N bits, the results of the
instruction are not written; instead, the status is
updated according to the instruction performed. There-
fore, the result of an instruction with the Status register
as its destination may be different than intended. As an
example, CLRF STATUS will set the Z bit and leave the
remaining status bits unchanged (‘000u u1uu’).

STATUS REGISTER
bit 7
Unimplemented: Read as ‘0’
N: Negative bit
This bit is used for signed arithmetic (2’s complement). It indicates whether the result was
negative (ALU MSB = 1).
1 = Result was negative
0 = Result was positive
OV: Overflow bit
This bit is used for signed arithmetic (2’s complement). It indicates an overflow of the
7-bit magnitude, which causes the sign bit (bit7) to change state.
1 = Overflow occurred for signed arithmetic (in this arithmetic operation)
0 = No overflow occurred
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
DC: Digit carry/borrow bit
For ADDWF, ADDLW, SUBLW and SUBWF instructions:
1 = A carry-out from the 4th low-order bit of the result occurred
0 = No carry-out from the 4th low-order bit of the result
C: Carry/borrow bit
For ADDWF, ADDLW, SUBLW and SUBWF instructions:
1 = A carry-out from the Most Significant bit of the result occurred
0 = No carry-out from the Most Significant bit of the result occurred
Legend:
R = Readable bit
-n = Value at POR

Note:
U-0

For borrow, the polarity is reversed. A subtraction is executed by adding the
2’s complement of the second operand. For rotate (RRF, RLF) instructions, this bit
is loaded with either bit 4 or bit 3 of the source register.

R/W-x
N
It is recommended that only BCF, BSF, SWAPF, MOVFF
and MOVWF instructions are used to alter the Status
register, because these instructions do not affect the Z,
C, DC, OV or N bits in the Status register.
For other instructions that do not affect status bits, see
the instruction set summaries in Table 24-2 and
Table 24-3.
Note:
R/W-x
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
OV
The C and DC bits operate as a borrow and
digit borrow bit respectively, in subtraction.
