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

Encoding:

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'.
