3  Introduction 

This specification describes a serial interface protocol for isochronous, fast and safe exporting of sensor data 
and simultaneous accessing of the slave registers.  

 

In the point-to-point configuration, only one device  with one slave (sensor) is operated  on the master. The 
BiSS  interface  is  hardware-compatible  to  the  SSI  interface  in  the  point-to-point  configuration  and  only 
requires two unidirectional differential lines.
