Don't shoot me if I'm wrong, as I have not worked with 6303 for several
years, but I think those instructions are present in the Hitachi 6303,
which was a 6803 derivative, if memory serves, it had no Y register, and
the XGDX instruction had a different opcode from the HC11, otherwise they
were code compatible.
