A microcontroller (MC) has integrated functional modules (FM) encompassing a first functional module (FM 1 ) which is configured so as to activate or deactivate interrupts (INT). High-frequency triggering events for interrupts are common especially in the preferred field of application of such microcontrollers, i.e. the equipment and operation of digital tachographs, because the signal of a speed sensor has to be recorded also at high speeds. This may affect the process stability when other request sequences are processed. In order to prevent this from happening, the first functional module (FM 1 ) deactivates an interrupt (INT) once requests (IRQ) have been processed and activates said interrupt (INT) again following a delay period (IED) that is associated with the interrupt (INT). The procedure combines the advantages of controlling processes by time intervals and the advantages of an interrupt controller.
