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

(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’.
