摘要： The present invention provides a communication system and a method for operating a communication system, said communication system having a CAN bus and at least two devices coupled by way of said CAN bus. Said device has a CAN control unit, an asynchronous serial communication (ASC) interface unit, and a switching means. Said CAN control unit is suited to transmit CAN data frames using a first physical protocol via said CAN bus in a first transmission mode. Said asynchronous serial communication (ASC) interface unit is suited to transmit ASC data frames using a second physical protocol via said CAN bus in a second transmission mode. Said switching means is configured to switch over between the first transmission mode and the second transmission mode as a function of at least one agreement applicable between said device and at least one further device.

摘要： The invention relates to a circuit configuration for the starter of an automotive internal combustion engine, said circuit configuration allowing the starter relay (4) to remain activated in the event of a short-term voltage dip (undervoltage of the battery). An integrated circuit memory (2) with a interlocking circuit (1) is interposed between a computer (19) and an output stage (3) that controls the starter relay (2). Upon undervoltage of the battery (20), said integrated circuit memory (2) maintains the status at a control input STEN during the voltage dip. A computer (19) that has gone back to a reset mode during the voltage dip is reactivated after termination of the voltage dip and controls the interlocking circuit (1) in such a manner that the starter relay (4) is continued to be controlled via the control input STEN. The integrated circuit memory is provided with an RC element in order to maintain a defined initial status of the flip-flop (14, 15) when the battery is re-connected.
