The ADV7610 CS/ pin description is "Chip Select (Bar). Pulling this line high causes the I2C state machine to ignore the I2C transmission" according to the datasheet.
The user guide ADV7610 UG-438 says to float this pin if unused (page 181) however the evaluation kit board schematic grounds this pin.
I need to have I2C transmission enabled normally during operation. Should I ground or float CS/ pin?
