MPC5644A DSI mode to drive TLE8718

I am trying to use MPC5644A to drive TLE8718, and TLE8718 requires MSC interface. So I set the DSPI on MPC5644A into DSI mode. The question is that I can not see the clock ouput and I don't know how to modify it.

I hope that you can provide a demo in which I can see how to configure SPI into CSI mode and to send a data .

 

To drive TLE8718, I have to send a command frame and then a data frame followed. In the datasheet , I find that I can only send a data frame using DSI , and I have to change the mode to SPI if I want to send a command frame, I don't know whether I am right.

 

If I want to send a SPI data, I know that I  just need to write data into DSPI_PUSHR. However, if I want to send a DSI data, what should I do? just write data into DSPI_ASDR?
