STM32F051 Continuous mode and Discontinuous mode explanation for the sequence conversion

The following illustrations present the differences among various configuration for continuous mode and discontinuous mode for 2 channels:

With both modes disabled: the conversion sequence start from the first channel until the last channel and then stop. Each time the channel conversion is done, the End of Conversion (EOC) interrupt flag will be triggered until the last channel, End of sequence (EOS) will be on.

 continuous mode disabled, and discontinuous mode disabled

With continuous mode enabled, and discontinuous mode disabled: similarly to single channel, the conversion process will be restarted automatically when the last channel is finished.

continuous mode enabled, and discontinuous mode disabled

With continuous mode disabled, and discontinuous mode enabled: Everytime the channel conversion is done, we need to trigger the start of ADC module again to move on to the next channel in the sequence.
