PURPOSE:To enable a simulated test without connecting an input/output device, by making transmission/reception of data with a computer system by a memory in the processing time of a set switch, when an address judging circuit detects the agreement of the address. CONSTITUTION:When the microprocessor 11 picks up the data from an A/D converter, the address assigned to the A/D converter is transmitted to the data and address bus 17 to access the memories 12, 13 and data transmission/reception is made with the input/output indication signal from the input/output control unit 15 to make input/output operation. If the A/D converter 18 is not connected as the input/output device, the address assigned to the A/D converter 18 is output, and if it is judged the same as the address set to the input/output device address set switch 23, the selector signal 213 is output and after the time required for data processing is elapsed, the pulse signal 204 and the data at the specified address are read out and transmitted, and program is executed between the computer system 1 and the test system 2. |
