ADV3002 detect input plugged

Question asked by loitran_gds on Aug 19, 2016

Hi all,

 

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,

Loi Tran
