I2C register access configuration inquiry

Dear specialist,

I have checked out your forum link: https://ez.analog.com/video/w/documents/773/adv7619-design-support-files

My interested working scenario is 0x80 rather than your example of "98 03 82 ; 24 bit SDR 422 Mode 0", can I reuse this golden example by only overriding address 0x03 with the data of 0x80? If not, could you help to provide some working register configuration with the format of 0x80?

Another question about the indirect subaddress accessing, if you designate the the address which is not in Page 0, for example, "98 FB 68 ; HDMI". How should I assign the new subaddress? Is 0x68 a 8-bit address or 7-bit address? From my trial, it seems to me an 8-bit address.

Following your golden example of ":02-07 720p,1080i,1080p In - 24-bit YCbCr 422 Out:" I couldn't make these indirect accessing work, I got those errors for the last part of your configuration when I was trying to follow your example.

  • The writes to address 72 are to a ADV7511 on another board.  If you are just dealing with the ADV7619 then you can ignore those writes.  These scripts are for a system with an ADV7619 and an ADV7511.

    Regarding 98 FB 68, the 68 is 8-bit addressing that the HDMI page will respond to.

    Changing 98 03 will change the output format as defined in the software manual.
