I use a MCU for control ADV3002 chip.
We need to detect that the device is plug or unplug in HDMI input port. Have some register in the datasheet indicate to control "hot plug detect" but no any register indicate the device is plug or unplug in input port. I can read that status by MCU IO from P5V_x pin or HPD_x pin of ADV3002 but I do not want to modify our hardware.
So what registers have indicated the device is plug or unplug in input port? And you can send me datasheet with more detail (many more registers).
Thanks & Best regards,
