1. A communication control device for a subscriber station of a serial bus system, comprising:
a communication control module configured to generate a transmitted signal for controlling a communication of the subscriber station with at least one other subscriber station of the bus system, in which bus system at least a first communication phase and a second communication phase are used for exchanging messages between subscriber stations of the bus system;
a first terminal for transmitting, in an operating mode of the first communication phase, the transmitted signal to a transmitting/receiving device which is configured to transmit the transmitted signal to a bus of the bus system;
a second terminal for receiving, in the operating mode of the first communication phase, a digital received signal from the transmitting/receiving device; and
an operating mode switching module configured to switch a transmission direction of the first terminal and the second terminal to the same direction in the second communication phase for differential signal transmission via the first terminal and the second terminal.
