I want to config the register of a chip through SPI module of MPC5744P.

I want to clear the register of address 0x06.

My relevant configuration code is as follows:


MC_ME.PCTL99.B.RUN_CFG = 0x0;        /* DSPI_0: select peri. cfg. RUN_PC[0]


SPI_0.MCR.R = 0x80010001; /* Configure DSPI_0 as master */
SPI_0.MODE.CTAR[0].R = 0x78AA0220; /* Configure CTAR0 */
SPI_0.MCR.B.HALT = 0x0; /* Exit HALT mode: go from STOPPED to RUNNING state*/

//the message I need to sent to the chip is 0x3400

SPI_0.PUSHR.PUSHR.R = 0x08013400;


are there any mistakes in my code?
