Preliminary
23.3.2.13 DSPI DSI Transmit Comparison Register (DSPI_COMPR)
The DSPI_COMPR holds a copy of the last transmitted DSI data. The DSPI_COMPR is read-only. DSI
data is transferred to this register as it is loaded into the TX shift register.
23.3.2.14 DSPI DSI Deserialization Data Register (DSPI_DDR)
The DSPI_DDR holds the signal states for the parallel output signals. The DSPI_DDR is read-only and is
memory mapped so that host software can read the incoming DSI frames.
