Abstract
A data input/output control unit for a touch panel interface device, comprising a touch panel for sensing coordinates of a point touched by a user's pen and generating an analog signal in accordance with the sensed result, a data detector for detecting input data to the touch panel, a control circuit for controlling a system operation in response to an output signal from the data detector, a switch for turning on/off supply power to the touch panel in response to a first control signal from the control circuit, an analog/digital converter for converting the analog signal from the touch panel into digital data in response to a second control signal from the control circuit and outputting the converted digital data to the control circuit, and a serial communication circuit for performing a serial communication with other systems in response to a third control signal from the control circuit.
