<p>PURPOSE: To write an adjustment value determined in each adjusting process in a nonvolatile memory in the one-chip microcomputer without increasing the cost of a product and the production cost of the product. CONSTITUTION: This system is equipped with a flash memory 1 where data can be erased and written, a CPU 6 which controls the system according to a control program stored in part of the flash memory 1, and a write controller 4 which operates to write data including the control program in the flash memory 1. When adjustments are made through plural adjusting processes by using an inspection device which detects plural adjustment values for correcting variance among individual products, the adjustment value is written in the flash memory 1 by the write controller 4 each time one adjusting process ends, and the CPU 6 controls the system by using the adjustment values.</p> |
