SPI Interface Example Project for ADSP-21489

Hi I am working with the ADSP-21489 (with the EZ-Kit Lite development board and CCES 2.6.0) for an audio application and was hoping to add control inputs via a SPI SAR ADC such as the MCP3208. 

 

Is there an example project that gives some guidance on how to use SPI to interface with slave devices from the development board? My main concerns are the pin configuration of the EZ-Kit and setting up a SPI callback to read the ADCs which would not interfere with the operation of the AD1939 codec. 

 

If you can provide an example or recommend any resources it would be much appreciated.
