PROBLEM TO BE SOLVED: To provide a communication data high-speed processing method that can surely capture data received externally at a high speed without affecting other functions. SOLUTION: The method includes a step where serial data sent externally re converted into parallel data and written in a FIFO memory 7, a step where a count is incremented by one every time data are written in the FIFO memory 7, a step where read processing is requested to a CPU 2 through interrupt processing every time data are written in the FIFO memory 7, a step where the data written in the FIFO memory 7 are read through interrupt processing after the read processing is requested, and a step where the count is decremented by one every time data written in the FIFO memory 7 are read.
