      ADC Interrupt flag.
      This flag is set when an ADC conversion result is ready to be read. An interrupt is invoked if the
      A/D interrupt is enabled. The flag must be cleared by software. It cannot be set by software.
      ADC Start and Status.
      Setting this flag starts an A/D conversion. The ADC logic insures that this signal is high while the
      ADC is busy. On completion of the conversion, ADCS is reset at the same time the interrupt flag
      ADCI is set. ADCS cannot be reset by software.
