The margin time shown in
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.

The SSC baud rate depends on the internal clock frequency.
Twelve internal digital clock cycles are necessary to ensure reliable operation. Therefore, the maximum SSC baud
rate depends on the external CLK.
3.9.3
A spike filter for all SSC lines can be selected via the SSC_FILT bit.
SSC Spike Filter Off
When the spike filter is disabled, each slope with 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.
SSC Spike Filter On
A sliding window with four consecutive sample bits is analyzed.
The sample frequency is:
Rising Edge Detect for SCK
•
•
Falling Edge Detect for SCK
•
•
Final Data Sheet
After a rising edge (LH combination), at least one of the two following samples must be high. Valid bit
A falling condition must be detected previously.
After a falling edge (HL combination), at least one of the two following samples must be low. Valid bit
A rising condition must be detected previously.
combinations: 0111 , 0110 , 0101.
combinations: 1000 , 1001 , 1010.
