A separate storage buffers exist for transmit (TXFIFO) and receive (RXFIFO) messages through a FIFO structure. Each buffer can store up to 64 messages. Once a message is written into the TXFIFO, the total delay to transmit it over the CAN bus is
2 x (TX driver delay + propagation delay + RX driver delay).
