F401RE - External analog reference

Hi All, just a simple question.

I'm working on Nucleo F401RE board with Mbed online IDE.

If I want to change analog reference from INTERNAL (3.3V) to an external reference (generated by me at 2.5V), what I have to do?

I only have to connect my reference (2.5V) on AVDD pin? Or there's something else to program?.

Thank you.

You can probably find that information in the reference manual. Maybe here: http://www.st.com/st-web-ui/static/active/en/resource/technical/document/reference_manual/DM00096844.pdf
