XORWF
Exclusive OR W with f
Syntax:
[label] XORWF f,d
Operands:
0 ≤ f ≤ 127
d ∈ [0,1]
Operation:
(W) .XOR. (f) → (destination)
Status Affected: Z

Description:
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'.
