PURPOSE:To produce no malfunction in an operation only by a target device by depriving the program control of a supported target device, inputting data from an external terminal equipment and controlling the input and output of program data by a monitor program. CONSTITUTION:After a power source is turned on, the control of the program after the reset of a microprocessor 21 is released by the program control depriving means 44 of a microcomputer development supporting device 4 connected to the target device 2 is shifted to the monitor program memory 45 of the microcomputer development supporting device 4. When the microcomputer development supporting device 4 is separated from the target device 2 according to the connection release of a control signal line 6, the program control depriving means 44 is invalidated and a start address after the reset of the microprocessor 21 is released is the program memory of the target device 2. Thereby, the malfunction is not produced even by the operation only of the target device. |
