MPC5777M DSPI problem

Hi,community:

I am a newer in MPC5777M. I want to configure DSPI as DSI mode, but I can not write 2'b01 to DSPI_0.MCR[DCONF]. It can be 00b once I write 01b to it, and I can not write access DSPI_0.ASDR0. Is there any sample code which can help me to understand how to configure DSPI to DSI/CSI mode?  Thx!

I made a screenshot from older manual, because in current version this table is broken. It is apparent you need to choose DSPI4/5/6 as only these module instances support serialization.

I have only tested with MPC5746R device. Example code you find here:
