Abstract:
1. A control unit for controlling and/or regulating at least one function in a motor vehicle, comprising: a controller arrangement, including at least one computing device and a serial multiwire interface; a serial multiwire bus; and at least one separate peripheral device connectable to the computing device via the serial multiwire bus, the peripheral device including an asynchronous single wire interface coupled between at least one output stage of the peripheral device and a serial multiwire bus interface of the peripheral device; wherein the serial multiwire bus interface of the peripheral device is connectable to the serial multiwire interface of the controller arrangement so that the peripheral device is capable of receiving serial data from the computing device transmitted over a data line of the serial multiwire bus and transferring the received serial data to the asynchronous single wire interface located in the peripheral device using a pin input of the serial multiwire interface of the peripheral device, wherein the asynchronous single wire interface is capable of converting the transferred serial data into universal asynchronous receiver/transmitter (UART) data and sending the UART data to the at least one output stage, and wherein there is no external single wire connecting the controller arrangement to the output stage of the peripheral device.
