I have a custom board that uses the 7842 and 7511 parts. The 7511 connects to a video processor that requires the active video horizontal and vertical resolution to be a multiple of 4. Is there a way I can read these values from the parts so I can verify this prior to enabling the 7511 outputs? I did a quick search of the data sheets and did not see a way to do this. To summarize, can I read the active video size from the 7842 or 7511?
