   13   A/D Converter block is a successive approximation analog-to-digital converter
   14   with a 12-bit accuracy. Up to eight analog input channels can be selected.
   15   Conversions can be performed in single or repeat mode. Result of the ADC is
   16   stored in a 32-bit data register corresponding to each channel.
