Patent ID: 8074118

Claim:
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 at least one debug interface, the debug interface having a monitoring functionality for observing memory content, the method comprising: detecting a first point in time at which a first value is written to a first memory cell, wherein the detecting is performed by the debug interface, obtaining, by the manipulation unit, a triggering point in time for a processing routine, wherein the triggering point is obtained based on information transmitted to the manipulation unit by the debug interface at the first point in time, and writing a second value to the first memory cell at a second point in time, wherein the second value is written to the first memory cell by the manipulation unit via the debug interface by using the processing routine, and wherein the second value is written to the first memory cell before the first memory cell is read by the control unit at a third point in time.
