0–15 Deserialized Data. When TSB configuration is set, the DESER_DATA field holds deserialized data
DESER_DAT which 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.
16–31 Deserialized Data. The DESER_DATA field holds deserialized data which is presented as signal
DESER_DAT states to the Parallel Output signals.

25.3.2.15 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.
