ADAU1978 configuration

Hi,

 I am going to use ADAU1978 audio codec. I have 3 MICs connected to 3 of the ADCs on the codec. I use I2C interface between the codec and STM3F407. What are the register settings that needs to be done?

I will be using the ADC as master. Also, I have a crystal of 12.288 Mhz which will be the master clock.Please help me with register settings.
