Zusammenfassung:PROBLEM TO BE SOLVED: To improve burst error resistance.SOLUTION: A serial interface port 30 detects a failure in a transmission route and selects all transmission lanes when the serial interface port 30 does not detect a failure. The serial interface port 30 selects a prescribed number of transmission lanes from the transmission lanes from which failures are not detected when the serial interface port 30 detects a failure. The serial interface port 30 generates a Cyclic Redundancy Check (CRC) for detecting an error from data to be transmitted in one transmission-reception cycle via the transmission lanes except any one transmission lane of the selected transmission lanes. The serial interface port 30 transmits data to be a transmission object via the transmission lanes except any one transmission lane of the selected transmission lanes and transmits the CRC in the same period as the data via the remaining one transmission lane.
