AbstractA for controlling a includes circuit a register for holding the repetition number of a program operation to be repeated, a counter receiving the content of the register and adapted to decrement in response with each execution of the program operation to be repeated, a memory for storing a sequence of instructions, and a controller for receiving an instruction read from the memory modification in a normal condition and to convert the received instruction into a no-operation instruction when the content of the counter becomes a predetermined content.
