Hello.

I have a question about lock detection of video input of ADV7181D.

 

I think we should use "in_lock" (Status 1 register bit 0) for detection of lock for video input.
I see following page.

The customer wants the CPU to know the lock of video input status by not S/W polling but INT pin.

 

Thank you!
Best regards.
