Abstract
An electronic unit includes a communication interface, a processor, a secure element, and a sub-system. The processor is connected to the communication interface by a first bus, to the secure element by a second bus and to the sub-system. The processor is designed to operate in a first mode, in which, at the second bus, it reproduces the signals received from the communication interface at the first bus. Also disclosed is a method carried out in such an electronic unit.
