CCS/LAUNCHXL-F28379D: May you give me some advice on how to use SPI of TMS320F28379D to drive DAC8564 to generate a sine wave?

Tool/software: Code Composer Studio

I am now programming on LAUNCHXL-F28379D to drive DAC8564/5 EVM.

I am trying to use  F28379D's SPI DMA funciton to driver DAC8654 to generate a sine wave.

As I see in the technical reference manual of F28379D that the SPI only support 1bit to 16bit word   during the transferring course  if I use the DMA function,

then how can I transfer the 24bit word once a time  which DAC8654  requires in its datasheet .

Do I have to use the method provided in the 39th page of the datasheet?

This seems a little diffucult for my sine wave appliation.

May you give me some advice on how to use SPI of TMS320F28379D to drive DAC8564 to generate a sine wave?

Thanks!
