• initiated by the occurrence of a second event, interrupting the execution of the first program part on the first arithmetic logic unit and then executing a second program part on the first arithmetic logic unit, wherein the second event and/or the second program part is/are assigned a second priority,
• wherein the second priority has a predetermined and in particular a user-defined relationship with the first priority, wherein the second priority is higher than the first priority,
