My question is with the recommended register settings for the ADV7611. There is a script file "ADV7611-VER.2.9.c.txt" It includes the recommended settings in addition to the recommendations in the PDF version 1.3. However, the "ADV7611-VER.2.9.c.txt" text file has settings the pdf doesn't. It also writes to a device address of 0x72. (28 writes). I can't find this device address anywhere in the Hardware Users Guide (UG-180.pdf), or Software Manual. And when I write to these addresses it doesn't return an i2c ACK. Is this 0x72 address for something else, or do I have a problem? Thanks for your help.
