ADV7627 can be written to, but not read from (I2C)

I am using the ADV7627 switching chip to pass HDMI through, and as I set up I2C to pass video through, I find that I cannot read from the chip whatsoever. I know I am able to write to it (at least partially) because I am able to pass video through it , but why can I not read the registers by I2C?


The reason I need to read the registers, I am trying to enable some functions, such as auto switching, and my MCU needs to know what flags are set off inside the ADV7627 in order to auto switch.


Thank you!
