Decode

Exclusive OR W with f

XORWF f {,d {,a}}

0 ≤ f ≤ 255

d ∈ [0,1]

a ∈ [0,1]

(W) .XOR. (f) → dest

N, Z

0001 10da ffff ffff

Exclusive OR the contents of W with

register ‘f’. If ‘d’ is ‘0’, the result is stored

in W. If ‘d’ is ‘1’, the result is stored back

in the register ‘f’ (default).

If ‘a’ is ‘0’, the Access Bank is selected.

If ‘a’ is ‘1’, the BSR is used to select the

GPR bank (default).

If ‘a’ is ‘0’ and the extended instruction

set is enabled, this instruction operates

in Indexed Literal Offset Addressing

mode whenever f ≤ 95 (5Fh). See

Section 26.2.3 “Byte-Oriented and

Bit-Oriented Instructions in Indexed

Literal Offset Mode” for details.
