MK64FN1M0VLL12 - Using an external voltage reference connected to VREF_OUT pin as the DAC reference.

Pg.133 of the K64 reference manual states that for K64 chips, VREF_OUT and VDDA are selectable as the DAC reference. VREF_OUT is the output pin of the internally generated 1.2 V voltage reference. Can an external voltage reference be used as the DAC voltage reference by connecting it to the VREF_OUT pin and selecting VREF_OUT as the DAC reference (with the 1.2 V internal voltage reference disabled)?
