The ADV7533 and ADV7535 are HDMI audio and video transmitters
|
|
compatible with HDMI 1.4 and DVI 1.0. They support color space
|
|
conversion, S/PDIF, CEC and HDCP. The transmitter input is MIPI DSI.

I2C slave addresses.
|
|
|
|
The ADV7533/35 internal registers are split into four pages
|
|
exposed through different I2C addresses, creating four register
|
|
maps. Each map has it own I2C address and acts as a standard slave
|
|
device on the I2C bus. The main address is mandatory, others are
|
|
optional and revert to defaults if not specified.
