<p>PURPOSE:To improve economic efficiency and to obtain flexibility, by controlling a response to an instruction signal with a microprogram, in an interface between a CPU and a console panel. CONSTITUTION:Since response control to an instruction signal from a console panel 2 is made with a microprogram provided in a CPU and the signal transmission between the CPU1 and the console panel 2 is done serially by using shifters 5 and 6, a command itself indicates the entry address of the microprogram. One signal line is enough for the operation because no decoding is required and the serial transmission is made, and also one driver/receiver is enough for the control.</p> |
