Abstract: A method and a device having a processor module for controlling operating sequences, in particular in an engine control unit in a motor vehicle, peripheral elements being selected by a processor module having a predetermined number of select interfaces by select signal output over these select interfaces, and instructions being transmitted to the peripheral elements over at least one information interface of the processor module. Selection identifiers are assigned to the instructions and transmitted together with them. Thus, a selection of peripheral elements is made by a select signal and a selection identifier.

Abstract: A device and method for identifying the version of integrated circuits IC is described, an ID, which indicates the respective version of the integrated circuit IC, being written in the form of at least one individually settable binary signal in a register R and being readable from the register R. The integrated circuit IC is constructed from multiple mask levels M1 to M5, at least one possible conduction path L2 being introduced through all mask levels M1 to M5 of the integrated circuit for each settable binary signal BS. The binary signal is settable according to whether the at least one conduction path through all mask levels conducts or is interrupted, means being contained which write the binary signal, which is set via the at least one conduction path, into the register. This method and this device may also be used for controlling operating sequences by a control unit.

Abstract: A method and a device are described for diagnosing a fuel system having a plurality of electric fuel delivery units, which are submerged on the inlet side in a fuel supply contained in a fuel tank, and which, on the outlet side, deliver fuel in a fuel line to an internal combustion engine. The currents of the electric fuel delivery units are measured directly or indirectly in an analysis unit, compared to one another, and a diagnostic signal in digitized form is generated as a function of the result of the comparison.

Abstract: The method and circuit arrangement and/or component prevents a change of a preset or set state of a control member and/or control unit (102) during a reset of controller or regulator (100) that controls this control member and/or control unit. The circuit arrangement and/or component (101) has at least one input and at least one output (TA) and is connected between at least one terminal (P) of a controller or regulator (100) and at least one input of the control member and/or control unit (102, 104). The at least one output (TA) of the circuit arrangement and/or component is connected for feedback to the at least one terminal (P) of the controller or regulator (100) and/or the at least one input of the circuit arrangement and/or the component (101), e.g. by means of feedback element (105), which may be a feedback resistor.
