XORWF
Exclusive OR W with f
Syntax:
[ label ] XORWF f [,d [,a]]
Operands:
0 ≤ f ≤ 255
d ∈ [0,1]
a ∈ [0,1]
Operation:
(W) .XOR. (f) → dest
Status Affected: N, Z
Encoding:
0001 10da ffff ffff
Description:
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 will be selected, overriding
the BSR value. If ‘a’ is 1, then the
bank will be selected as per the
BSR value (default).
