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 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).
