<p>PURPOSE:To prevent errors due to the shift of timing of an asynchronous strobe signal and breaks of waveform, by adjusting automatically a circuit, which generates the asynchronous strobe signal required for a processor, with a managing processor to hold always its delay time in a prescribed value. CONSTITUTION:The control program of a managing processor MP initializes a setting register 105 to a standard value and turns on a test cycle request signal TCY to set a flip-flop 1 and operates a delay loop circuit. Thereafter, the processor MP monitors FFs 102-104 to confirm whether the delay valve is a prescribed value or not. If it is not the prescribed value, the set value of the register 105 is so changed that the delay value becomes the prescribed value.</p> |
