Example:

Exclusive OR Literal with W

[ label ] XORLW k

0 ≤ k ≤ 255

(W) .XOR. k → (W)

Z

11

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.

Example

Exclusive OR W with f

[ label ] XORWF f,d

0 ≤ f ≤ 127

d ∈ [0,1]

(W) .XOR. (f) → (dest)

Z

00

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'.
