Abstract: An electronic unit comprises a microcontroller with a control input, a control output, and a signal input; and an interface circuit with a connection terminal, a control output, a control input, and a signal output. Both the microcontroller and the interface circuit each have a first operating mode and a second operating mode. The microcontroller is designed to cause the interface circuit to operate in its first operating mode. The interface circuit is designed to convert an input signal into a derivation signal representing a derivation of the input signal over time and to generate a control signal from the derivation signal. The microcontroller is designed to cause the interface circuit to operate in its second operating mode and to receive and convert a digital input signal and to output an output signal to the microcontroller.
