WRITING METHOD FOR TIME DATA

摘要

PURPOSE:To easily set a real time in a production process by connecting a 2nd timepiece IC where the real time is set to an equipment and writing real- time data in a 1st timepiece IC from the 2nd timepiece IC. CONSTITUTION:A microcomputer 3 is connected to the timepiece IC 2 and a microcomputer 3 sets the real time in the timepiece IC 2. Then the microcomputer 13 selects the timepiece IC 2 of a real-time setting circuit A and its real- time data is read out and stored temporarily in the microcomputer 13. Then the microcomputer 13 selects the timepiece IC 12 on the side of electric equipment 12 immediately this time and writes the real-time data in the timepiece IC 12. Consequently, the data can be written in real time in the electric equipment in the manufacture process.
