Specification

Final Data Sheet

V1.1, 2010-05

Figure 13

SSC Spike Filter

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)
