PROBLEM TO BE SOLVED: To transmit a synch break signal without changing the baud rate of transmission data in serial communication using an LIN communication protocol. SOLUTION: A microcomputer 100 outputs a high level signal from a synch break exclusive port P1 during 13 bits at starting the transmission of a message frame. A synch break generating circuit 300 generates the synch break signal from the output signal, and inputs it to the TX terminal of an LIN driver circuit 200. Afterwards, the microcomputer 100 inputs any signal other than the synch break signal of the message frame to the TX terminal of the LIN driver 200. COPYRIGHT: (C)2004,JPO
