    SUPPORTED FEATURES:
      - IO Read/write : Set/Reset and Read (Polling/Interrupt)
      - Joystick: config and Read (Polling/Interrupt)
      - Touch Screen Features: Single point mode (Polling/Interrupt)
      - TempSensor Feature: accuracy not determined (Polling).

    UNSUPPORTED FEATURES:
      - Row ADC Feature is not supported (not implemented on STM3210C-EVAL board)
