Exclusive OR literal with W
[ label ] XORLW k
0 ≤ k ≤ 255
(W) .XOR. k → (W)
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 ≤ 31
d ∈ [0,1]
(W) .XOR. (f) → (dest)
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’.
