ADC1/ADC2 configuration options differs from ADC3 on STM32H723

Hi All,

I want to use two ADCs on STM32H7 configured equal, but using one DMA each, and measuring on different channels. However it seems like the ADC3 have options ADC1 and 2 doesn't have. In this case DMA continuous request.

Is this intentional? A workaround?

Best regards!
