[Icc-mot] Re: XGate support

[Gene Norris]

Jim,

Yes. However, you cannot use the xgate coprocessor reliably with the
current assembler.

First you must select the s12x processor and then make a CUSTOM device
configuration. Richard's default for the dp512 expanded memory is WRONG.

Edward has a good map and header file for the dp512. I think he could be
coaxed into providing a link to them. He may also share his opinion of
the xgate assembler. (Edward, I can provide space on our server if you
cannot.)

I have had some paging issues, but Edward seems to have no problems.
