Claim:
1. A timer module of a control unit, comprising: at least one output module; at least one input module; at least one logic module; and a routing unit to interconnect the modules; wherein an output signal to be checked is read in to the input module, wherein the output signal to be checked includes an output signal of the output module, wherein the signal characteristics for the output signal to be checked are determined in the input module, wherein the logic module reads the signal characteristics from the input module, wherein the logic module compares the signal characteristics to at least one comparison value, a signal length of the output signal being compared as the signal characteristics, in that in the input module time stamp values are assigned to the signal flanks of the output signal and a difference of the time stamp values is compared to a permissible maximum value, wherein the routing unit interconnects the modules and, which due to blocking requesting and transmitting of data, provides interrupt functionality without a separate interrupt controller, and wherein the routing unit enables each of the modules, which are connected to the routing unit, to have any number of routing unit write channels, which are data sources, and any number of routing unit read channels, which are data sinks, so that the routing unit provides that any of the data sources may be connected to any of the data sinks.
