Draft
The margin time in following table is the time between write access to the SSC Data Line
and the earliest possible sample read of the TLE5010 itself for read back.
It is useful to have a maximum distance between 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 therefore a rising and a falling edge.
