During the data phase of a FDCAN transmission only one node is transmitting, all others are receivers. The length of the bus line has no impact. When transmitting via pin FDCAN_TX the protocol controller receives the transmitted data from its local CAN transceiver via pin FDCAN_RX. The received data is delayed by the CAN transceiver loop delay. If this delay is greater than TSEG1 (time segment before sample point), a bit error is detected. Without transceiver delay compensation, the bit rate in the data phase of a FDCAN frame is limited by the transceiver's loop delay. Since this parameter is related to the transceiver used, there cannot be a default value, and it must be explicitly defined with the configuration variable CONFIG_FDCAN_DEVICE_TRANSCEIVER_LOOP_DELAY.
