20.3.2.12 DSPI DSI Alternate Serialization Data Register (DSPIx_ASDR)
The DSPIx_ASDR provides a means for host software to write the data to be serialized. When the TXSS
bit in the DSPIx_DSICR is set, the data in the DSPIx_ASDR is the source of the serialized data. Writes to
the DSPIx_ASDR take effect on the next frame boundary.

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]. Refer to
Section 20.4.4.6, “DSPI Connections to eTPU_A, eTPU_B, EMIOS and SIU.”
