1. A subscriber station for a serial bus system, comprising:
a communication control device configured to control a communication of the subscriber station with at least one other subscriber station of the bus system; and
a transceiver device configured to send a transmit signal produced by the communication control device as a frame to a bus of the bus system, such that for a frame that is exchanged between subscriber stations of the bus system, a bit time of a signal sent to the bus in a first communication phase differs from the bit time of a signal sent in a second communication phase;
wherein the communication control device is configured to produce the transmit signal, in a first operating mode, for a first frame that is configured according to a specified communication protocol with which other subscriber stations in the bus system communicate, and
wherein the communication control device is configured to produce the transmit signal, in a second operating mode, for a second frame that assigns to at least one bit a different function than is assigned to the bit in the specified communication protocol.
