ADC device in case of resource re-mapping conflict. This allows a single ADC device to be used for all channels, which can free up DMA channels. For the H7 this makes much more sense because the TEMP and VREF channels are ALWAYS on ADC3, so using ADC3 for other pins is optimal. The previous behaviour was to use the first instance for that supported the pin. This behavour is only used when the configured default DMA device does not support the pin. e.g. ``` possible. ``` The above config would no-longer use ADC1 for anything, as ADC2 and ADC3 can satisfy all the ADC requirements.
