METHOD FOR AVOIDING DEFECT IN CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a method for avoiding defect in a control program for reducing an excess cost and delay of schedule by avoiding the defect even when the defect occurs in the control program in a non-rewritable memory and a correction of the program is required. SOLUTION: The method avoids only the defect portion to execute alternatively a corrected module by using a part of a flash memory to store the module in which the defect of the program is corrected to an arbitrary address when the defect occurs in the control program stored in a mask ROM in a CPU.
