I don't think I fully understand what you mean. If you are asking if it
is possible to have text and graphics on the screen simultaneously, then
the answer is yes. I played with one of these a few years back so I
don't remember the details now, but I do believe that text and graphics
together is possible as long as there is enough RAM.

After reading this a few more times, I think I understand now. You are
saying that the FS pin affects the appearance of the graphics that are
displayed when you toggle it. I think I remember something like this
happening to me as well, but that was so long ago I don't recall for
sure. It should be documented in the datasheets, did you read them
thoroughly?
