BiSS INTERFACE MASTER
preliminary
The CRC start value does affect the CRC result. The
CRC start value can be used to safely differentiate be-
tween two SCD data words e.g. two position words
provided by two different sensors. The same CRC start
value that is used in the sensor needs to be applied in
the master to check the received single cycle data. A
typical default slave CRC start value is 0x0000.
iC-MB4 can read sensors and control actuators. The
ACTnSENS parameter defines the functionality of each
BiSS slave on the BiSS bus.
Actuator control requires the MO signal.
