Abstract:
An electronic vehicle controller comprising:a processor unit; a communication output stage for coupling the controller to a databus; and a data protocol device connected between the processor unit and the communication output stage; wherein said data protocol device variably sets a data protocol to be used for a respective data transfer, as a function of protocol control information which is supplied as an input to said data protocol device; and the data protocol device comprises a transmission block having a predeterminable number of data input channels on a processor unit side thereof, a predeterminable number of data output channels on a bus side thereof, and means for transposing data from the input channels to the output channels, which means include a transmission multiplexer stage that emits at least one data transmission control signal as a function of a set data protocol; and a reception block having a predeterminable number of data input channels on a bus side thereof, a predeterminable number of data output channels on a processor side thereof, and means for transposing data from the input channels to the output channels, which means includes a reception multiplexer stage that emits at least one data transmission control signal as a function of the data protocol.
