In the spec it says we can select 1.25V 2.5V or 5V as voltage reference. Is this only possible by manually changing reference voltage on the pin ? Or is it possible to select an internal reference voltage?
Hello,
Well, it is hard to comment, as you did not shared which device you are referring to.

For eQADC you can only have 5V reference.
VRH must be same as VDDA, and VDDA is 5V.
