The margin time shown in
Line and the earliest possible sample read of the TLE5011 itself for read back.
It is useful to have a maximum distance between the WRITE and subsequent READ.
This ensures a reliable read back of the written data for the Slave-Active Byte
generation.

8.2
The SSC Baud rate depends on the internal clock frequency.
12 internal digital clock cycles are necessary to ensure a reliable operation. Therefore,
the maximum SSC Baud rate depends on the external CLK.
8.3
A SSC Spike Filter for all SSC lines can be selected via the SSC_FILT bit.
8.3.1
When the spike filter is disabled, each slope of a rising voltage is used to define a bit.
This is independent of the length of the sampled pulse. For example, a positive spike
generates a rising and a falling edge.
