Is it possible for SigmaStudio to communicate with other chips via SPI?

I have an ADAU1701 on a EVAL-ADAU1701MINIZ.


We can program it via the USB interface and I2C easy enough.


We want to know if we can use the SPI interface to communicate with another processor for further processing.


Our program has done the hard bit that we wanted a DSP for, but is now full and we can't fit a bigger program onto it. Can we send the DSPs output to another processor via the SPI to do the final bit of number crunching?


SPI is mentioned occasionally in the datasheets for the ADAU1701 and the EVAL-ADAU1701MINIZ but never in enough detail to figure out how to set it up.
