I am using a pair of ADV212 chips in master/slave mode to decode incoming
compressed video and send it to an FPGA. The data sheet and User guide only
say to connect SCOMM5 to the same GPIO of the host. But what do I do with it
and with what timing? Is it a frame sync, and enable, or what? Can you please
point me to any documentation that describes how this pin should be used?
