A serial interface circuit is compatible with a three-wire interface, but uses only one or two wires. One wire is a data signal line. The other wire, if present, is a scan signal line or clock signal line. If only one wire is used, the serial interface circuit detects the start of a communication period by detecting a synchronization pattern, and generates a clock signal, approximately synchronized to the clock signal used at the partner interface circuit, by dividing a higher-frequency clock signal. The partner interface circuit can operate as if a three-wire interface were being used.
