How to config MPC5674F DSI slave to receive 32 bit frame

[longlongago]

1. I have config the DSPIA as dsi master mode ,and set frame size to 32 bit with setting TSBCNT = 31;

2. I can capture the ware conrrectly that send by DSPIA.

3.Connect DSPIA and DSPIB inner,SIU.DISR.R = 0x00540000; 

4.I do not know how to config DSPIB to receive  32 bits frame.

I am not sure what you would like to achieve. 32-bit frames can only be used with TSB i.e. for serialization.

I recently made example code for DPSI serialization here:

I am studying dsi in 5674F ,now ,I have config DSPI_A as dsi master that can be send 32bit frame by setting " DSPI_A.DSICR.B.TSBC = 1;DSPI_A.DSICR1.B.TSBCNT = 31;"  I just want to receive the frame by DSPI_B,but by read DSPI_B.DDR.R ,only can ready 16 bit data sending by DPSI_A.
