10 STM32 ADC is a successive approximation analog-to-digital converter.
12 in single, continuous, scan or discontinuous mode. Result of the ADC is
13 stored in a left-aligned or right-aligned 32-bit data register.
17 voltage goes beyond the user-defined, higher or lower thresholds.
19 Each STM32 ADC block can have up to 3 ADC instances.
