Abstract

PURPOSE:To execute an efficient control by providing a holding circuit for holding a digital signal stored in a memory circuit between the memory circuit and a D/A converter. CONSTITUTION:A holding circuit 9 is connected between a memory circuit 4 and a D/A converter 5. The holding circuit 9 holds the value stored in the memory circuit 9 until it loads the value stored therein next and outputs the held value to the converter 5. A setting circuit 10 is connected to the holding circuit 9 to replace the held value in the holding circuit 9 with new value according to the output from the setting circuit 10. Therefore, the holding circuit 9 does not cancel a digital signal stored in the past but holds the signal unless the set signal is applied from the setting circuit 10 to the holding circuit 9 and the digital signal stored in the memory circuit 4 is loaded to the holding circuit 9, and converted by the converter 5 into an analog signal value 7 corresponding to the digital signal and holds the output from the converter 5.
