APPARATUS FOR PROCESSING KEY INPUT USING INTERRUPT

摘要

PURPOSE: A key input processing apparatus which uses an interrupt is provided to identify an input key in case an interrupt is generated and to process the identified input key. CONSTITUTION: A key input signal generating unit(120) includes first and second resistances and is connected to an input key(110). A key interrupt signal generating unit(130) includes a logic circuit and is connected to the input key. A control unit(140) is connected to the key input signal generating unit and the key interrupt signal generating unit. The key interrupt signal and the key input signal are inputted to the control unit.
