Abstract

　本発明は、マイクロコンピュータが少ない数のポートで多くのスイッチの状態を検出することが可能な技術を提供することを目的とする。本発明に係るマイクロコンピュータシステムでは、Ｍ個の押下式スイッチ（ＳＷ１２，ＳＷ１３，ＳＷ１４，ＳＷ２３，ＳＷ２４，ＳＷ３４）のそれぞれには、マイクロコンピュータ（１）のＮ個の入力ポート（ＩＰ１～ＩＰ４）の組み合わせに係る（２N－１）種類の組み合わせパターンのいずれか一つが互いに異なるように割り当てられている。各押下式スイッチは、押下されると、割り当てられている組み合わせパターンにおける入力ポートの入力レベルを反転させる。マイクロコンピュータ（１）は、Ｎ個の入力ポートの入力レベルに基づいて、各押下式スイッチの状態を検出する。
