We are using ADV7391 which is getting the input from the camera. We need to give the 8bit data, hsync, vsync as input to the chip. The ADV7391 which configured by the I2C. I went through the design support of analog signal and found ADV7403_XC3S400_ADV7391-VER.1.2c.txt script to configure the ADV7391. As per the datasheet the address is 0x54. But in the script I seen that some register are mentioned with 0x42 address and some of the registers are mentioned in the ADV7391 datasheet also. Do we need to configure that registers also or do i need to configure the registers that only mentioned with 0x54 address. Please help me here.
