0–31 Alternate Serialized Data. The ASER_DATA field holds the alternate data to be serialized.
ASER_DATA
25.3.2.13 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.
The DSPI_COMPR is a 32 bits register, the upper 16 bits are only used, when TSB is enabled. For non
TSB configurations only the least 16 significant bits are used.
Address: DSPI_BASE + 0xC8
Access: Read Only

25.3.2.14 DSPI DSI Deserialization Data Register (DSPI_DDR)
The DSPI_DDR register holds the signal states for the Parallel Output signals. The DSPI_DDR is
read-only and it is memory mapped so that host software can read the incoming DSI frames.
