ADV7619 reset through I2C writing of 0xff with 0x80 fails

Hello Specialist,

We found that ADV7619 reset through I2C writing of 0xff fails all the time, actually, it seems the reset behavior happened indeed as I can find the register configuration is replaced with the default. However it is concerning to me that why I am always ending up with a write failure. I have set my physical reset as the invalid value of high.

Error: Write failed
