How to modify the MOSI of S32R274?

I need to send 8 bytes command at a time, as the Correct.PNG.

But the SPI_PUSHR  can only send 2 bytes TXDATD at a time, and after the SPI_PUSHR sent the TXDATD, the MOSI will be pulled high, as the Incorrect.PNG.

Is there a way to solve the problem of MOSI pull high?

Thanks!

Dear Peter:

Thank you for your reply!

But the document only refers to the control of PCS, I have finished this part.

In the reference manual, the SOUT is also pulled high between the two transfers.

Is there a way let SOUT pulled low between the two transfers?

Thanks!

B.R.

Don
