ADAU1467 Bidirectional I2S Port Connection and configuration

Hello all,

In my project, I'm using the EVAL-ADAU1467Z to evaluate the DSP.

The codec included on the EVB, has separate, one-way ports for the input and output signals:

I plan to use a codec with a single I2S bidirectional port (BCLK, LRCLK, DATA IN, DATA OUT lines).

How should I configure/connect the LRCLK_IN, BCLK_IN pins?

The way I see it, there are three options:

1-  Codec in slave mode, and the DSP will in master mode:

2- Codec in slave mode, and the DSP in master mode:

3- Codec in master mode, and the DSP in slave mode:

What is the right way to do it?

Many thanks
