Subtract W from f
[ label ]
0
d
(f) - (W)
Subtract (2’s complement method)
W register from register 'f'. If 'd' is 0,
the result is stored in the W regis-
ter. If 'd' is 1, the result is stored
back in register 'f'.
Subtract W from Literal
[ label ]
0
k - (W)
The W register is subtracted (2’s
complement method) from the
eight bit literal 'k'. The result is
placed in the W register.
Swap Nibbles in f

0
d
(f<3:0>)
(f<7:4>)
None
The upper and lower nibbles of
register 'f' are exchanged. If 'd' is
0, the result is placed in W regis-
ter. If 'd' is 1, the result is placed in
register 'f'.

0
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'.
Exclusive OR Literal with W
[ label ]
0
(W) .XOR. k
Z
The contents of the W register
are XOR’ed with the eight bit lit-
eral 'k'. The result is placed in
the W register.
