STATUS Register
The STATUS register, shown in Register 6-2, contains
the arithmetic status of the ALU. The STATUS register
can be the operand for any instruction, as with any
other register. If the STATUS register is the destination
for an instruction that affects the Z, DC, C, OV or N bits,
then the write to these five bits is disabled. These bits
are set or cleared according to the device logic. There-
fore, the result of an instruction with the STATUS
register as destination may be different than intended.
For example, CLRF STATUS will clear the upper three
bits and set the Z bit. This leaves the STATUS register
as 000u u1uu (where u = unchanged).
It is recommended, therefore, 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 not affecting any Status
bits, see Table 24-2.
Note:
The C and DC bits operate as a Borrow
and Digit Borrow bit respectively, in
subtraction.
REGISTER 6-2:
STATUS REGISTER
U-0
R/W-x
—
—N
OV
Z
DC(1)
C(2)
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 7-5
Unimplemented:
Read as ‘0’
bit 4
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
bit 3
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 (bit 7) to change state.
1
= Overflow occurred for signed arithmetic (in this arithmetic operation)
0
= No overflow occurred
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(1)
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
bit 0
C:
Carry/Borrow bit(2)
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
Note 1:
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.
2:
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 the high or low-order bit
of the source register.
