hello, do you have the demo software which configured the DSPI in  simplified SPI mode without TXFIFO and RXFIFO ?

I have some problems about the configuration of DSPI in simplified SPI mode .

Below is the MPC5744P SPI Demo:

SPI_2.PUSHR.PUSHR.R = 0x00001234; /* Initialize slave DSPI_2's response to master */
SPI_1.PUSHR.PUSHR.R = 0x08015678; /* Transmit data from master to slave SPI with EOQ */
read_data_DSPI_2(); /* Read data on slave DSPI */
read_data_DSPI_1(); /* Read data on master DSPI */

 

I not sure that if the transmit commands need to write to PUSHR register? And about 0x5678, is the 0x78 transmit first or the 0x56 transmit first?
