Claims (2)
- 複数のキーが配列されたキーパネルと、
前記キーパネルをスキャンして、前記キーの押下状態に関するキースキャン情報を取得する外部回路と、
前記外部回路と独立して動作し、前記外部回路と送受信可能に接続されたCPUと、
を備え、
前記外部回路は、通常モードとスリープモードとを有し、通常モード中にいずれかのキーが押下されると、割込信号を前記CPUに送信して前記キースキャン情報を前記CPUに送信するとともに、前記押下されたキーが所定のキーの場合には自らでスリープモードに移行し、スリープモード中では前記所定のキーが押下された場合にのみ、前記割込信号および前記キースキャン情報を前記CPUに送信するとともに自らで通常モードに移行する、
ことを特徴とするスリープ機能付き電子機器。 - 任意の前記キーを前記所定のキーとして設定自在となっている、
ことを特徴とする請求項1記載のスリープ機能付き電子機器。
