SPI Emulation using SPORTs  (adsp-21469)

is it possible to emulate full-duplex SPI communication via SPORTs?


I have already dedicated 2 available SPI ports as SPI masters.

I need additional SPI slave. I guess if this is possible I would need

2 SPORTs for this job (which I do have available).


The emulated SPI via SPORT on adsp-21469 will be used as a slave

to communicate with additional microcontroller (used as SPI master).


I read EE-244 and EE-248 and didn't find a way for full-duplex SPI communication there.

Does somebody has any example or pointers how to proceed?
