Abstract
A data bus interface for a control unit, in particular for a motor vehicle control unit is described, as well as a control unit, in particular a motor vehicle control unit, having a data bus interface for accessing a data bus for communicating with another control unit via the data bus. A data bus interface may be used with a particularly high degree of flexibility and be manufactured economically. The data bus interface includes two arithmetic units, in particular two microprocessors, which communicate with each other via an internal data bus; and two transceivers which are connected either to the same external data bus or to two different external data buses and are interconnected with the two arithmetic units in such a way that the two arithmetic units are connected either to the same external data bus or to the two different data buses.
