V 0.46, 2009-09

Another possibility is a 3-pin SSC Interface with bidirectional open-drain data line, serial clock signal and chip

select. This setup is designed to communicate with a microcontroller in a bus system, together with other SSC

slaves (e.g. two TLE5012 for redundancy reasons). This mode can be activated using bit SSC_OD.

SSC Inactive Time (CSoff)

The SSC inactive time defines the delay time after a transfer before the TLE5012 can be selected again.
