Audio Codec on CycloneII DSP Kit

I have a CycloneII DSP Development kit and want to write data to the TI TLV320 audio codec chip on the board. I don't see an existing way to do that with the original full feature design. I try...

Thank you, BadOmen, for your help! I can now talk to the audio codec control interface using SPI. Now I need to talk to the data interface referred to as the digital audio interface in the TLV320AIC23B spec. in order to send (or receive) audio data to be played (or captured).

Does anyone know of any Altera examples that interface to the TI AIC23b audio codec? I'm thinking of using a lpm_shiftreg, but then I still need to get the clocks and other signals synchronized. The codec has 4 different modes for its digital audio interface - right justified, left justified, I2S, and DSP mode. The DSP mode is "compatible with the McBSP ports of TI DSPs." Does anyone know of a McDSP component that I can drop into my Cyclone II part? I'm open to any other suggestions.

Regards,

Dave
