Hi ,

thanks Ghassan.  Could not find a blog either. What puzzels me is that we have good search criteria and still don't find anything.
That level of detail looks like a MOS note. The details match with our experience and seem to make sense. Could it be a note that was unpublished?

Regards

Lothar
