In the past I have tested DSPI serialization what’s already configuration similar to microsecond bus (on this device the feature is called timed serial bus TSB):

Microsecond bus protocol consist additional features to the SPI. These would be needed to configure and add to mentioned example and you will get MSC example:
1 ) serialization of internal timers
2) LVDS terminal pairs (positive and negative) for data output and clock
3) changes in data format
For SOUT and SCLK it is needed to choose and configure pins properly according excel sheet embedded to the device’s RM.
