    摘要: The electronic device comprises a microprocessor (μC) having a data input (IN), having a data output (OUT) and having a control input (CTL), as well as at least one memory unit (MEM) which is formed, in particular, by means of a persistent memory module. The microprocessor has at least two operating modes which can be selectively activated via the control input and is set up to execute at least one predefined sequential program in a first operating mode in order to process digital data arriving via the data input and/or in order to output digital data at the data output and is set up to be reprogrammable in a second operating mode such that at least one value of a parameter which influences the execution of the at least one sequential program by the microprocessor can be changed. The memory unit is also set up to react to each activation of the second operating mode with a change of memory contents, Z, such that said memory contents, Z, represent a frequency with which the second operating mode has been activated inside a predefined period of time.
