11 / 43 page Data Sheet 11 Rev. 1.0 2015-06-12 TLE9222 Functional Description 4.2 Communication Controller Interface The communication controller interface is the link between the TLE9222 and the FlexRay communication controller, comprising three digital signals: • TxEN (Transmit Data Enable Not) input • TxD (Transmit Data) input • RxD (Receive Data) output The logical I/O levels of all three digital pins are adapted to the VIOdigital reference voltage supply. Figure 4 FlexRay physical layer bus signals The communication controller interface drives the serial digital data stream available on the TxD input to the FlexRay bus via the transmitter. Simultaneously the receiver of the TLE9222 monitors the data on the FlexRay bus and transfers the data to a serial digital data stream back to the RxD output.
