Use MSP430G2553 internal reference voltage at an output pin

Hi,

I want to map the internal reference (2.5V) of the ADC to an output pin.

It is possible as describe here (if I understand it correctly):

http://forum.43oh.com/topic/5985-use-msp430g2553-internal-reference-voltage-at-an-output-pin/

But I was unable to find a way to do it in Energia.

I found something interesting in the driverlib, but I have no idea how to use it.

https://github.com/energia/Energia/blob/master/hardware/msp430/libraries/DriverLib/utility/ref_a.c

Hopefully someone can point me in the right direction.
