User station for a serial bus system, and method for communicating in a serial bus system

A bus system, comprising:

• a bus;
• and
• at least two user stations that are connected to one another via the bus in such a way that they may communicate serially with one another, and of which at least one user station includes a user station including:
• a receiver configured to receive a signal from the bus of the bus system, in which bus system at least one first communication phase and one second communication phase are used for exchanging messages between user stations of the bus system, and
• a device configured to evaluate a digital reception signal that is output by the receiver, the receiver being configured to generate a digital reception signal from the signal received from the bus and to output the digital signal to the device at a terminal, the device being configured to evaluate the digital reception signal with regard to a predetermined communication protocol that establishes when a predetermined communication phase of the first and second communication phases, which indicates a subsequent transfer of useful data in a message, begins and ends, and the device being configured to reverse a data flow of the digital reception signal to the receiver at the terminal for a time period of at least one bit when the evaluation of the device shows that data at that time are being received from the bus in the predetermined communication phase.

A method for communicating in a serial bus system, the method being carried out using a user station for a bus system, in which at least one first communication phase and one second communication phase are used for exchanging messages between user stations of the bus system, the user station including a receiver and a device, the method comprising the following steps:

• receiving via the receiver a signal from the bus of the bus system;
• generating via the receiver a digital reception signal from the signal received from the bus and outputting the digital reception signal to a terminal;
• evaluating via the device the digital reception signal with regard to a predetermined communication protocol that establishes when a predetermined communication phase of the first and second communication phases, which indicates a subsequent transfer of useful data in a message, begins and ends;
• and
• reversing, via the device, a data flow of the digital reception signal to the receiver at the terminal for a time period of at least one bit when the evaluation of the device shows that data at that time are being received from the bus in the predetermined communication phase.
