ABSTRACT:
A CPU outputs a signal from an output port group, and receives an input signal from input port group, whereby a pressed key of input key group is detected. When there are a plurality of keys which are pressed, CPU selects a key with priority based on valid key information in a ROM, and stores code data of the selected key in a key code portion. Consequently, only one of the plurality of keys pressed simultaneously is selected as an input key.
