But I would not be so sure that you can select reference value, as I also don't see such field in HAL... | |

On almost every ARM it should also be possible. I've looked at the linked reference manual, but I can't even find how to select an input channel. In STM32L011 the regiter is called ADC_CHSELR, but I can't find anything like that in the reference manual. If this is a very new part then it can take some time before the manual and datasheet "stabilize". | |
