Exclusive OR Literal with W
[ label ] XORLW k
0 ≤ k ≤ 255
(W) .XOR. k → (W)
Z
11
The contents of the W register
are XOR’ed with the eight bit
literal 'k'. The result is placed in
the W register.

0 ≤ f ≤ 127
d ∈ [0,1]
(W) .XOR. (f) → (dest)
Z
00
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'.
