Classification: CPC H  G | IPC G  H

Claim 12:
13. A communication control device for a user station of a serial bus system, comprising:
a communication control module configured to generate a transmission signal for controlling a communication of the user station with at least one other user station of the serial bus system, in which serial bus system at least one first communication phase and one second communication phase being used for exchanging messages between user stations of the serial bus system;
a first terminal for sending the transmission signal to a transceiver device which is configured to transmit the transmission signal onto a bus of the serial bus system;
a second terminal for receiving a digital reception signal from the transceiver device;
wherein the communication control device is configured to generate an additional signal that indicates to the transceiver device that a switch is to be made from a present operating mode into another operating mode of at least three different operating modes, and that achieves an internal communication between the communication control module and the transceiver device, and the communication control module is configured to send the additional signal, in the digital reception signal, to the transceiver device via the second terminal, and the communication control module is configured to receive, via the first terminal, feedback in the transmission signal from the transceiver device regarding a changeover of the operating mode that has taken place as a result of the operating mode changeover signal, and to evaluate the feedback.
