Abstract

PURPOSE:To ensure an easy reproduction of an address designation before the power supply is turned off, by always storing a designated address in an address storing circuit which is energized by a battery and holds an address data. CONSTITUTION:A memory 1 stores plural data to give a control to a digital control machinery such as a program oscilloscope or the like. An address circuit 2 designates the address of the memory 1, and an address control circuit 3 changes the address designation. Furthermore an address storing circuit 5 stores the address designated by the circuit 2. In addition, the following parts and circuits are provided: a stand- by power supply battery 14; a power supply recovery signal generating circuit 21 which corresponds to the circuit 2; and an address signal shift control circuit 22 that shifts the address signal stored in the circuit 5 to the circuit 2 in response to the power supply recovery signal generated from the circuit 21.
