I have a question about the HPA pins in the ADV7619 part.
If two HDMI ports are connected, and with both HPA_A and HPA_B be asserted, or will only the currently selected HDMI port’s corresponding HPA be asserted?
The idea is that we want to use the HPA to trigger an LED so the validation engineer can see which HDMI port they are using. Obviously this will only work if only the selected HDMI ports HPA is asserted. If both of them are always asserted regardless of the selected port then this won’t work.
