PURPOSE: To make compact, light in weight, and inexpensive an input/output interface device connected to an interface in which common adaptation to each kind of peripheral equipment and intersystem communication can be attained.HOSHINO TAKAYUKI干野 隆之ODA YOSHIAKI小田 好明...
PURPOSE:To obtain an input/output interface device having optional bit length, and also to economically repair it when it is faulty, by connecting plural output unit elements and input unit elements in cascade. CONSTITUTION:Connection of mutual unit elements is executed between a series data input...
THE INPUT-OUTPUT INTERFACE DEVICE IS MOUNTED BETWEEN A DATA SWITCH AND A PLURALITY OF INPUT AND OUTPUT DATA TRANSMISSION CHANNELS. THE DATA ARE PROCESSED IN THE SWITCH BY "PACKETS" AND TRANSMITTED ON THE TRACKS BY "FRAMES". IT INCLUDES A LINE STATUS EXPLORER CYCLICALLY EXPLORING THE CLOCK TRANS...
and port data write signal is generated by using the interface signal of a printer port, and a general I/O bus 14 constituted of 8 output data buses, 6 address buses, 4 input data buses, and 1 interrupt control signal is constructed, and plural quickly controllable I/O ports can be dir...
PROBLEM TO BE SOLVED: To make the control substrate of an input output device common by making it possible to select an interface connection depending upon a main body device to be connected and setting the control substrate so that interface output signals can be connected. SOLUTION: A CPU 5...
PROBLEM TO BE SOLVED: To provide a sound input/output(I/O) interface device which can always monitor the state of a sound storing memory without having to switch mode, evaluate a fault state and judge whether a system can be operated. SOLUTION: The sound I/O interface device has a memory...
INPUT-OUTPUT INTERFACE CIRCUIT, INTEGRATED CIRCUIT DEVICE AND ELECTRONIC APPARATUS An input-output interface circuit of the present invention includes an input-output terminal, an input buffer, a first MOS transistor of a first conductivi...
