XORWF

Exclusive OR WREG with f

Syntax:

[ label ] XORWF f [ ,d [,a] ]

Operands:

0 ≤ f ≤ 255

d ∈ [0,1]

a ∈ [0,1]

Operation:

(WREG) .XOR. (f) → dest

Status Affected: N,Z

Encoding:

0001 10da ffff ffff

Description:

Exclusive OR the contents of

WREG with register ’f’. If ’d’ is 0, the

result is stored in WREG. If ’d’ is 1,

the result is stored back in the reg-

ister 'f' (default). If ’a’ is 0, the

Access Bank will be selected, over-

riding the BSR value. If ’a’ is 1, the

Bank will be selected as per the

BSR value.
