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, over-
riding the BSR value. If ‘a’ is ‘1’, then
the bank will be selected as per the
BSR value (default).
