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).
