Dear Friends,
I am cross posting this from Keil/discuss site, I hope nobody minds.

Does any one know how to declare variables and structures to use all the available internal ram in P89C669FA, Philips calls them with various names such as XDATA, EDATA, HDATA etc, and keil calls them XDATA, far etc, I am not able to force the compiler to recognize the EDATA from 7F:0100 to 7F:04FF a lot of searching on the net has not yielded any solution.

I have read their, data sheets, user manuals, 51MX architecture manual, Cx51 manual and could not find a solution.

Using this chip has become a real pain!

Regards,
John.
