1. A device suitable for incorporation as a module in a CAN system having a bus connection, the device comprising:

  • a microcomputer;

    an oscillator that generates a number of different frequencies in response to directions from the microcomputer;

    a transceiver; and

    a Controller Area Network (CAN) Controller coupled to the oscillator,wherein the CAN controller is coupled to the bus connection via the transceiver andwherein the oscillator that generates a number of different frequencies clocks for the CAN Controller and a reference frequency that is compared with the variable clock frequency and adapts the module to any CAN bit time.
