1. A method for influencing a control unit by a manipulation unit, the control unit having a microcontroller a memory having a plurality of memory cells and a debug interface, the debug interface having a monitoring functionality for observing memory content,comprisinga first point in time of the control unit for writing a first value to a first memory cell is detected by means of the debug interface, and a triggering point in time for a processing routine by the manipulation unit is obtained as the result by means of the information transmitted by the debug interface at the first point in time to the manipulation unit, and at a second point in time, a second value is written to the first memory cell by the manipulation unit by the debug interface by the processing routine before the first memory cell is read by the control unit at a third point in time.
