SM Bus documentation for E4690?

looking for command byte info for SM Bus programming on E4690

I have been asking our local rep for SM Bus info for months, but of course have gotten no response back to him from ATI.

Does anyone have the command byte info for the E4690 or any other fairly recent RadeonHD GPU?

 

Thanks!!

Hi

Just for your information I'm in the exact same situation as you are. I opened a detailled thread here : http://devgurus.amd.com/thread/158825

Thomas - did you see the app note that was posted on EDG a few months ago about accessing the LM63?

I asked AMD about the LM63 access and they posted that note.  But, they claim that those are the only registers available on the SMbus and that is clearly wrong.
