PROBLEM TO BE SOLVED: To eliminate the influence of a noise in a request signal transmission line or an acknowledge signal transmission, and to increase the reliability of a bus system using a multiplex bus. SOLUTION: In a data transmission source and a data transmission destination, a noise interrupt signal with a specific pattern different from a noise pattern is transmitted before a request signal REQ or an acknowledge signal ACK to the other party are transmitted, so that the other party can receive, from the specific pattern state of the noise interrupt signal to be received before the reception of those signals REQ and ACK, a signal following the specific pattern as a request signal REQ or an acknowledge signal ACK.
