30.3.2.15 DSPI DSI Configuration Register 1 (DSPI_DSICR1)
The DSI Configuration Register 1 selects various attributes associated with TSB configuration. The user
must not write to the DSPI_DSICR1 while the DSPI is in the running state. If TSB configuration is not
used, the register value is ignored.

Field Description
DESER_DATA Deserialized Data. When TSB configuration is set, the DESER_DATA field holds deserialized data that is
presented as signal states to the parallel output signals. If TSB is disabled, these bits are ignored, and only the
lower 16 bits are valid.
