Hi @paul_ephraim_13,
ADC_StartGroupConversion will start the SW conversion of all channels of the requested ADC channel group.

Adc_Interrupt Selects whether the interrupt for each ADC Unit will be enabled. For each Adc HW unit, there are 2 interrupts that can be enabled:
- End of Conversion.
- Watchdog interrupts.
These settings are used for optimizing the code size by removing the interrupt handling code for interrupts that are not needed.
Best regards,
Julián
