Abstract
PURPOSE: To obtain an expected value from standard units and to increase the efficiency of function inspection, by providing terminals and circuits for comparison inspection.
CONSTITUTION: The output of an oscillation circuit 2 provided at a wiring board 1 is input to FF circuits F1WF3 forming clock pulses to form internal clock signals ϕ1Wϕ3. A circuit G is provided with a terminal P2 inputting pulse signals. Further, a terminal P1 receiving the control input signal from the circuit G is provided. Thus, the control input closes the circuit G to inhibit the transmission of oscillation output and the pulse signal from an inspection unit is fed from the terminal P2. Further, the gate circuit in a control unit as a standard product is similarly controlled and the pulse signal from the insepction unit is input to the terminal P2. Moreover, a reset input terminal P3 of the FF circuits F1WF3 is provided, and when a reset signal is input to the terminal from an inspection unit commonly, the phase of clock signal between inspected product and the standard product can be made in agreement.
