ことを特徴とするシリアル伝送回路。[Claims for Utility Model Registration] A serial transmission circuit that converts parallel digital data into a serial signal and transmits the serial signal, including a transmitter that transmits data, a receiver that receives data, and a connection between the receiver and the transmitter. It has a first transmission path that connects and transmits data, and a second transmission path that connects the transmitting section and the receiving section and transmits a clock, and transmits the serial signal received by the receiving section to its internal buffer. The transmitter detects that the clock on the second transmission path has been stopped by stopping the clock transmitted on the second transmission path based on a reception status signal generated when the clock is captured. A serial transmission circuit characterized in that the transmission of data is stopped.
