Abstract

PURPOSE:To easily set a data and also to execute the overall operation at a high speed by a simple and inexpensive constitution, by selecting the number of variables held in each stage, in accordance with an address designating signal, and sending it out as a signal for designating the number of variables. CONSTITUTION:When a strobe signal is applied from a terminal ST, a data having the number of variables of 2 bits is held by each stage ST0-ST3 of a register RG from data input terminals DI0-DI7, and its holding output is provided to an input of a selector SL being equivalent to a 2-circuit and 4-contact type switch. In the selector SL, said data is controlled by upper 2 bits of an address designating signal which is sent out from an address counter CUA, selects in order each holding output of the stages ST0-ST3, and is sent out as a variable number designating signal from data output terminals DO0, DO1.
