Abstract:
1. A data bus interface for a control unit of a motor vehicle control unit, the interface comprising: two arithmetic units which directly communicate with each other via an internal data bus without the use of an intervening memory; and two transceivers which are configured to be selectively both connectable to a same external data bus and each connectable individually to a different one of two different external data buses, the two transceivers being interconnected with the two arithmetic units in such a way that the two arithmetic units are configured to be selectively both connectable to a same one of the two transceivers and each connectable to a different one of the two transceivers; wherein a receiving terminal of a second of the two arithmetic units is connected via a jumper element to a connecting line between a receiving terminal of a first of the two arithmetic units and a terminal of a first of the two transceivers, and wherein if the two arithmetic units are connected to the same external data bus, the jumper element is closed, and if the two arithmetic units are connected to the two different external data buses, the jumper element is open.
