AREF on lattepanda alpha?

I have very unstable results when using analogRead on the latte panda alpha. If I connect 3.3V on say A0, the read value ranges from 677 to 689 and sometimes it is worse.
It is not good for my application.
If I look at the atmega32U4 datasheet, there is a AREF, but I don't see it on the lattepanda alpha pinout.
Is there a way to use external supply for the analog reference?
Thanks,
