A method for monitoring a clock generator module of an electronic circuit which is configured to generate a plurality of clock signals for the electronic circuit. A monitoring module external to the circuit alternately causes the selection of one of the clock signals in the circuit as a selection signal; wherein based on the selection signal a PWM signal, whose period duration and holding time are predetermined, is generated and output; wherein the PWM signal is received from the electronic circuit by the monitoring module and measured using a monitoring clock signal to determine at least one measurement result, the at least one measurement result is compared with at least one comparison result or comparison result range, and a malfunction of the clock generator module is determined if the at least one measurement result does not match the at least one comparison result or comparison result range.

Method for monitoring a clock generator module of an electronic circuit

A method and an apparatus for allocating configuration inputs of a microcontroller, the apparatus being embodied in such a way that at each configuration input, one signal state of at least two possible signal states is to be set, wherein there is connected to each configuration input one respective energy source that can assume at least two states, in order to set the at least two signal states at each configuration input, a setting arrangement being provided with which the states of each energy source are controlled in such a way that the predefined signal state exists for each configuration input.
