Exclusive OR Literal with W
[ label ] XORLW k
0 ≤ k ≤ 255
(W) .XOR. k → (W)
Z

1010 kkkk kkkk
The contents of the W register
are XOR’ed with the eight-bit
literal ‘k’. The result is placed in
the W register.

0110 dfff ffff
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’.
