  • detecting a start of frame symbol on the communication bus;

    determining a length of the start of frame symbol;

    detecting a start of a synchronization field on the communication bus;

    determining a length of an adjusted synchronization field;

    determining if the length of the adjusted synchronization field is less than the length of the start of frame symbol; and

    if the length of the adjusted synchronization field is less than the length of the start of frame symbol, concluding that the start of frame symbol is valid and concluding that the synchronization field is valid.
