ADV7611 keep free-running if resolution changes

Hi, i would like ADV7611 to keep free-running in the exact same mode (with blanking info and everything) if the resolution changes, but not if the framerate or blanking info changes. So i need a way to detect input resolution changes via interrupt, program the free run mode to match the input resolution if the resolution is ok for the sink (FPGA), and then if the source disconnects or changes resolution, the ADV7611 should keep free running in the configured resolution/blanking, but if the source just changes blanking periods, the ADV7611 should take on those settings.

 

What are the I2C registers for this ?
