Subtract W from f
[ label ] SUBWF f,d
0 ≤ f ≤ 127
d ∈ [0,1]
(f) - (W) → (destination)
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’.

None
The upper and lower nibbles of
register ‘f’ are exchanged. If ‘d’ is
‘0’, the result is placed in the W
register. If ‘d’ is ‘1’, the result is
placed in register ‘f’.
The contents of the W register

are XOR’ed with the eight-bit
literal ‘k’. The result is placed in
the W register.

Exclusive OR W with f
[ label ] XORWF
0 ≤ f ≤ 127
d ∈ [0,1]
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’.
