How to Set DSP’s Instruction and Program it

Hello,

I am in hot water and how to program DSP in ADAU1772.

I have read ADAU1772 (The ADAU1772 Datasheet is given: http://www.kynix.com/uploadfiles/pdf/ADAU1772BCPZ.pdf ) audio codec datasheet,however,there is no any informations about how to set DSP’s instruction and program it. Well,there is a guide for evaluaton board with ADAU1772 but I do not have that board. What’s more,pins of my ADAU1772 are permanently connected to FPGA So I have to program it using FPGA.

I need information which registers inside audio code that I should write and what is the possible instruction. It’s sad that I can not find any information on Analog Devices Website.

Any people here help me?  Any advice will be appreciated!
