15.1.2 Features
Features of the ADC module include:
• Linear successive approximation algorithm with 12 bits resolution
• Up to 28 analog inputs
• Output formatted in 12-, 10- or 8-bit right-justified format
• Single or continuous conversion (automatic return to idle after single conversion)
• Configurable sample time and conversion speed/power
• Conversion complete flag and interrupt
• Input clock selectable from up to four sources
• Operation in wait or stop3 modes for lower noise operation
• Asynchronous clock source for lower noise operation
• Selectable asynchronous hardware conversion trigger
• Automatic compare with interrupt for less-than, or greater-than or equal-to, programmable value
