Hi,

 

In "ADV7619_RecSetting.pdf" page 6 of 12, the recommended value is 0x03 (HDMI block ,add:0xC0).

 

firstly, we set the 0x03.

And secondly, we read back the data to check the wrote data.

 

but the read back data is 0xFF.

is this resister "write only" resister?

 

this resister is not defined in Data sheet. so please teach us the data type.
