DSPI slave operation is only supported for a single master and single slave on the device. Timing is valid for
that case only.
2
Input timing assumes an input slew rate of 1 ns (10% - 90%) and uses TTL / Automotive voltage thresholds.
3
All timing values for output signals in this table, are measured to 50% of the output voltage.
4
All output timing is worst case and includes the mismatching of rise and fall times of the output pads.
