(f) - (W)
Subtract W from f
[ label ] SUBWF f,d
0
d
Subtract (2’s complement method) W
register from register 'f'. If 'd' is 0, the
result is stored in the W register. If 'd' is
1, the result is stored back in register 'f'.
Subtract W from Literal
[ label ] SUBLW k
0
k - (W)
The W register is subtracted (2’s com-
plement method) from the eight bit lit-
eral 'k'. The result is placed in the W
register.
Swap Nibbles in f
[ label ] SWAPF f,d
0
d
(f<3:0>)
(f<7:4>)
None
The upper and lower nibbles of regis-
ter 'f' are exchanged. If 'd' is 0, the
result is placed in W register. If 'd' is 1,
the result is placed in register 'f'.

d
(W) .XOR. (f)
Z
Exclusive OR the contents of the W
register with register 'f'. If 'd' is 0, the
result is stored in the W register. If 'd'
is 1, the result is stored back in
register 'f'.
(W) .XOR. k
Z
Exclusive OR Literal with W
[label]
0
The contents of the W register are
XOR’ed with the eight bit literal 'k'.
The result is placed in the W
register.
