Filter for DATA and CS
The following conditions apply:
• The DATA pin has a ’2-of-3’ filter
• The CS input has a ’2-of-3’ filter that suppresses only positive spikes
3.9.4 SSC Data Transfer
The following transfer Byte are possible:
• Command Byte (to access and change operating modes of the TLE5011)
• Data Bytes (any data transferred in any direction)
• CRC Byte (cyclic redundancy check)
• Slave-active Byte (response of all selected slaves)
