CC3220SF-LAUNCHXL: SPI Slave blocking read function

Part Number: CC3220SF-LAUNCHXL

Hi,

My TI wifi chip (CC3220SF-LAUNCHXL) is using the SPI bus slave interface.

I a thread that can wait on a transaction initiated by the SPI master.

I am looking for a blocking read function that returns when data is available.

However, there does not seem to be any driver level read functions for the SPI slave.

Any suggestions on how I can implement this function?

Thanks.
