<p>PURPOSE: To read data corresponding to respective programs of microcomputers into one non-volatile memory in the microcomputer device provided with the main microcomputer, the sub-microcomputer, and the non-volatile memory. CONSTITUTION: Data corresponding to respective programs of a main microcomputer 11 and sub-microcomputers 12 and 13 and discrimination codes corresponding to these programs are written in a non-volatile memory 2. The main microcomputer 11 reads out data and the discrimination code from the nonvolatile memory 2; and if the discrimination code is a preliminarily determined value, the main microcomputer 11 performs the processing based on this data. But if is not a preliminarily determined value, the main microcomputer 11 transfers this data and the discrimination code to sub-microcomputers 12 and 13. Only when the transferred discrimination code is a preliminarily determined value, sub-microcomputers 12 and 13 perform the processing based on transferred data.</p> |
