Abstract: In a method for operating a heatable exhaust-gas sensor, which supplies at least one measuring signal and in which a sensor heater is operated using a pulse-width modulated operating voltage, the detection of the at least one measuring signal has priority over the supply of the pulse-width modulated operating voltage for sensor heater, and at least during a predefined time window in which the measuring signal is detected, the supply of the pulse-width modulated operating voltage for the sensor heater is suppressed using a blocking signal.

Abstract: A method for exchanging data between a first and at least one second user of a network, the data being exchanged via frames in which during execution of a request by the first user to the at least one second user for a number of k payload data, a read instruction for an nth payload datum is transmitted in at least one nth frame to the at least one second user, and in which all available bits of an immediately subsequent (n+1)th frame are used for directly transmitting the nth payload datum in a response of the at least one second user to the first user.

Abstract: A method for testing an integrated circuit and an integrated circuit. The integrated circuit has an internal testing structure which may be accessed via an internal test access port and a control bus which is conducted to the outside via control ports, it being possible to switch over between a running mode and a test mode so that, in the test mode, the test access port is accessed via the control ports and the control bus, thus testing the integrated circuit.
