adsp-21479 and adau1978

Question

Hello, 
 I have a question about connecting an adau1978 to an adsp-21479. 
 I want to connect the adau1978 to the dsp using the Input data port (IDP). 
 Is this possible? or do I need a sport interface!? 
 Which settings should I use for the adau1978 to output the data in the correct format. 
 Is there any example code available?! 
 Kind regards, 
 Sander

Hi Sander, 
 Sorry for the delay in getting back on this. I assume that you are referring to the part ADAU1977. Yes. It should be possible to connect the ADC outputs to IDP of ADSP-21479. IDPs can receive the data in all the serial mode of operation. In case you need to use the TDM mode of ADAU1977 then the SPORTs are the only interface which needs to be used. 
 I do not have the IDP example code for the ADSP-21479 processors. I have one for ADSP-21375 processors. You may need to add an additional bit which is supported on ADSP-21479 processors to make this code work in ADSP-21479.
