3 STM32 ADC is a successive approximation analog-to-digital converter.
4 It has several multiplexed input channels. Conversions can be performed
5 in single, continuous, scan or discontinuous mode. Result of the ADC is
6 stored in a left-aligned or right-aligned 32-bit data register.
10 voltage goes beyond the user-defined, higher or lower thresholds.
12 Each STM32 ADC block can have up to 3 ADC instances.
16 - regular conversion can be done in sequence, running in background
17 - injected conversions have higher priority, and so have the ability to
