PURPOSE: To provide a single interface controller for controlling communication between IIOC and a host computer without the need of an exclusive micro processor.
CONSTITUTION: The multiplex transmission bus controller adjusting input is provided. The controller does not need the exclusive micro processor for input filtering, input change detection, and a processing for serial-parallel/parallel- serial I/O data conversion. The controller provides output refreshing and input data over-sampling for removing noise connected to a data line. Data which is over-sampled is filtered and a signal received from an input device is de- bounced. Input data is converted from series to parallel for detecting whether any change exists or not from a previous input data stream and it is checked. When the change of input is detected, the host micro processor is interrupted.
