SUBLW
Subtract W from Literal
Syntax:
[ label ]
SUBLW k
Operands:
0
k
255
Operation:
k – (W)
W)
Status Affected: C, DC, Z
Description:
The W register is subtracted (two’s
complement method) from the
eight-bit literal ‘k’. The result is
placed in the W register.
SUBWF
Subtract W from f
Syntax:
[ label ]
SUBWF f,d
Operands:
0
f
127
d
[0,1]
Operation:
(f) – (W)
destination)
Status Affected: C, DC, Z
Description:
Subtract (two’s complement
method) W register from register ‘f’.
If ‘d’ = 0, the result is stored in the
W register. If ‘d’ = 1, the result is
stored back in register ‘f’.
SWAPF
Swap Nibbles in f
Syntax:
[ label ] SWAPF f,d
Operands:
0
f
127
d
[0,1]
Operation:
(f<3:0>)
(destination<7:4>),
(f<7:4>)
(destination<3:0>)
Status Affected:
None
Description:
The upper and lower nibbles of
register ‘f’ are exchanged. If
‘d’ = 0, the result is placed in W
register. If ‘d’ = 1, the result is
placed in register ‘f’.

XORLW
Exclusive OR Literal with W
Syntax:
[ label ]
XORLW k
Operands:
0
k
255
Operation:
(W) .XOR. k
W)
Status Affected:
Z
Description:
The contents of the W register
are XOR’ed with the eight-bit
literal ‘k’. The result is placed in
the W register.
XORWF
Exclusive OR W with f
Syntax:
[ label ] XORWF
Operands:
0
f
127
d
[0,1]
Operation:
(W) .XOR. (f)
destination)
Status Affected:
Z
Description:
Exclusive OR the contents of the
W register with register ‘f’. If
‘d’ = 0, the result is stored in the
W register. If ‘d’ = 1, the result is
stored back in register ‘f’.
