PURPOSE:To prevent the faulty operation of a transducer and stabilize the device by a method wherein a program output prepared beforehand by an instruction output switching circuit is impressed on the transducer during a period wherein a memory is rewritten. CONSTITUTION:The device has a constitution wherein an instruction output switching circuit 600 is interposed between a memory 200 and a transducer 400. When the level of a load signal input terminal LD is shifted from 0 to 1, the output of the circuit 600 appearing at output terminals 600g-600a is fixed unambiguously at 1,000,000. This state continues while the level of the terminal LD is 1, and after this level is shifted to 0, the output of the memory 200 is transmitted to the transducer 400. In this way, the program output 1,000,000 prepared beforehand by the circuit 600 in impressed on the transducer 400 during a period wherein the memory 200 is rewritten. Accordingly, faulty operations of the transducer can be eliminated by setting the output of memory 200 to be equal to the program output prepared by the circuit 600. |
