    • The invention is directed to a circuit for processing a signal (UL) of a lambda probe having a probe signal terminal on which the signal (UL) is outputted and a probe ground terminal. The circuit includes a voltage source having a plus pole and having a minus pole connected to the probe ground terminal. A first network of passive components is connected between the plus pole and the probe signal terminal for dividing the voltage between the plus pole and the probe signal terminal in a pregiven ratio thereby providing a divided potential as a first analog signal. An analog-to-digital converter has an input and is connected to a chassis ground at a ground potential different than the ground potential at the probe ground terminal. A second network of passive components is connected to the plus pole for supplying a potential proportional to the potential on the plus pole as a second analog signal. The input of the converter is directly connected to the first network to receive the first analog signal and to the second network to receive the second analog signal thereby facilitating digital processing of the first and second analog signals in the converter.

    • A method for completely reprogramming an erasable, non-volatile memory (12) in a control device (10) is presented. The control device (10) has at least one central unit (11), a volatile memory (13), an erasable, non-volatile memory (12) and also input/output circuits (15). The data to be programmed are transferred from an external electronic device (18), such as a personal computer for example, to the control device (10). The control device then programs the received data itself into the erasable, non-volatile memory. With the method, the erasable, non-volatile memory (12) is divided into two areas (20, 21) that can be erased and programmed separately. Before the actual programming operation a programming module is written in each case into each area (20, 21). To reprogram the erasable, non-volatile memory (12), the programming module is written into at least one of the areas (20, 21) that can be erased and programmed separately. The programming of one of the two areas (20, 21) takes place only if the programming module is written in the other of the two areas (20, 21) that can be erased and programmed separately.

    • A microcomputer (10) is proposed, which includes a central processing unit (11), a non-volatile memory (13), a volatile memory (14), a monitoring circuit (12) and also an input/output unit (16). Two different operating states are possible in the microcomputer (10). In the first operating state, the microcomputer executes a program which is located in the non-volatile memory (13). In the second operating state, the microcomputer (10) executes a program which is located in the volatile memory (14). The monitoring circuit (12) effects a resetting of the microcomputer (10) whenever it does not receive a monitoring signal for a predetermined time (watchdog timer). The microcomputer is distinguished in that it includes an element for suppressing monitoring signals which are always active whenever the microcomputer (10) is operating in the second operating state.
