Abstract

A user station for a serial bus system. The user station includes a communication control device for controlling a communication of the user station with at least one other user station, and a transceiver device to serially transmit a transmission signal, generated by the communication control device, onto a bus, and serially receive signals from the bus. The communication control device generates the transmission signal according to a frame and inserts into the frame two check sums that include different bits of the frame in the computation. The communication control device inserts dynamic stuff bits into the frame in such a way that an inverse stuff bit is inserted into the bit stream of the frame after 5 identical bits in succession. The communication control device computes the two check sums so that a maximum of one of the two check sums includes the dynamic stuff bits in the computation.
