Using SPI on DAI pins with ADSP-21469

Hi,

 

I was wondering if it is possible to route the four lines of a SPI bus (CLK, MISO, MOSI, FLAG) to DAI pins instead of DPI pins. I have a board design that connects the four SPI lines of a slave SPI device to DAI_P1, DAI_P2, DAI_P3, and DAI_P4 of the 21469. Is it possible to configure the SRU/SRU2 such that these DAI pins are driven by the SPI peripheral?

 

Thanks for any help.

 

Matt
