Newbie question for stm32H723 adc

[Niramas]

I am just getting started with the stm32h723 ADC.    If I create a regular sequence group of several input channels, how does my ISR know which channel was sampled last (which channel's data is in the DR)?  I don't see this in the registers.

Thanks,

Typically you'd DMA a group of channels into an array, and then get an interrupt for some multiple of them.

So I have to go down another rabbit hole to get my ADC data?   Is there a code example for the ADC-DMA transfer?
