PROBLEM TO BE SOLVED: To transfer data in a short transfer time without error. SOLUTION: A main CPU 2 divides a command into three blocks and outputs them to a sub CPU 3. When the sub CPU 3 receives all data outputted from the main CPU 2, the sub CPU 3 switches an output of OPTION from "Low" to "High". The main CPU 2 measures a reception completion time from the output of the three blocks to switching of the output of OPTION to "High" and when the reception completion time exceeds an error discrimination time, an error is detected. When the main CPU 2 detects the error, the main CPU 2 resends the command to the sub CPU 3. COPYRIGHT: (C)2004,JPO
