FEATURES   
■ Three Standby Modes (Typical)
    – STOP - 2 µA
    – HALT - 0.8 mA
    – Low Voltage Standby (<VLV)
■ Expanded Register File Control Registers
■ Special Architecture to Automate Both Generation and
    Reception of Complex Pulses or Signals:
    – One Programmable 8-Bit Counter/Timer with Two
        Capture Registers
    – One Programmable 16-Bit Counter/Timer with
        One Capture Register
    – Programmable Input Glitch Filter for Pulse
    Reception
■ Five Priority Interrupts
