    摘要: An I/O expansion device for additional inputs and outputs, and an apparatus and a methed for applying this device. The device includes a connector (CN1) for the connection with a parallel port, a plurality of 4-bit input/output ports, and an I/O expansion circuit (100) having a 4-bit data bus for data transfer between a plurality of 4-bit input/output ports and the connector. The I/O expansion circuit (100) includes a control input CTRL including a strobe PROG for controlling fetch of the command for selecting the input/output ports and an operation mode, a data input DIN that recieves a command in accordance with the state transition of the strobe PROG and data to be transferred to the input/output port selected by the command, and a data output DOUT for giving the state of the selected port through the connector.

    摘要: A storage device (200) has a memory and a circuit (100) which has a data input (Din), a control input (CTRL) and a data output (Dout), and provides an address input from the data input (Din) to the memory in accordance with a control signal from the control input (CTRL), so that the storage device (200) stores the data at the address in the memory or outputs data at the address in the memory to the data output (Dout). The apparatus provides the control signal to the control input (CTRL) from the interface (PORTS, P0, P1, P2), address and the data to the data input (Din) from the interface (PORTS, P0, P1, P2), to store the data at the address in the memory or to output data at the address in the memory to the data output (Dout). The apparatus may have a microcontroller (MPU) in which the interface (PORTS, P0, P1, P2) is provided.
