Abstract: PURPOSE:To stop the execution of a program instruction with an optional timing by providing a gate circuit which is controlled by a prescribed control signal at an output part of an instruction decoder circuit. CONSTITUTION:The output signal of a control matrix ROM is delivered via NOR gate circuits G1-G4 respectively. These gate circuits are controllingly opened and closed by the output signal of an OR gate circuit which receives a delay signal DL which requests a temporary stop of actions, a reflesh signal RF, a bus request signal BR, a sleeve signal SL, etc. An action stop request signal is produced with the timing where a microinstruction action of one or several steps is through to a program instruction which is under execution. Then the request signal is supplied to the circuit G5. Thus the output of the circuit G5 is set at ''1'' and at a high impedance, and the circuits G1-G4 are fixed at ''0''. These gate circuits can be held in a non-operation state as long as the action stop request signals are continuously produced.
