20.3.2.11 DSPI DSI Serialization Data Register (DSPIx_SDR)
The DSPIx_SDR contains the signal states of the parallel input signals from the eTPU or the eMIOS. The 
pin states of the parallel input signals are latched into the DSPIx_SDR on the rising edge of every system 
clock. The DSPIx_SDR is read-only. When the TXSS bit in the DSPIx_DSICR is negated, the data in the 
DSPIx_SDR is the source of the serialized data.
The following table describes the field in the DSPI deserial serial interface serialization data register:

[15:0]
Serialized data. The SER_DATA field contains the signal states of the parallel input signals. SER_DATA [15:0] maps 
to DSPI serialization inputs IN[15:0]. See Section 20.4.4.6, “DSPI Connections to eTPUA, eTPUB, eMIOS and SIU.”
