audio codec config

There is a soundmax audio codec, from the analog devices. AD1981B

It can be configuring only via the I2S interface, which is the audio stream interface also.

The soundmax codecs have only short datasheets, with electrical char, registerdefs, and package dimensions. there is no other info.

How should I configure the codec? Have I embed the control data to the audio stream, on the serial bus? how? how can it detect it? how produces it the output in that time, when it gots the command, except the audio data?
