Hi ADI Expert,
May I set ADV748X 8-bit digital port as tri-state output when not use?
Thanks very much for your suggestion!
You can tristate the pixel output pins by setting TRI_PIX (IO Map Reg 0x0E) to 0b1 and you can tristate the LLC output by setting TRI_LLC (IO Map Reg 0x0E) to 0b1.
Please refer to the ADV7481 Register Control Manual (UG-747) available here for details:
Before moving in to your question, Could you please answer the following?
1. Do you have one of our evaluation board for ADV748X?
2. How do you configure the board?
3. Are you using any specific script from ADV748X design support files?
Sorry I don't have evaluation board of ADV748X.
Due to now is still under schematic design stage, and customer would like to know whether can they set 8-bit digital port as tri-state then they can save video switch on they board.
So in this stage, I haven't use any specific script on to configure ADV748X.
We are checking with part specialist on this and update you soon.
Good day, have you got part specialist's feedback for this question? Thanks!
