K28 VDDA pin for adc conversion power down

If I want to save power and only use the adc's in the K28 very little meaning once ever couple of days can I power down this interface by floating it or tying it to ground to save the 215ua of current the data sheet says is the minimum current consumption? Reading through the data sheet it looks like VDDA is only used for the ADC logic correct? I did get info on another post saying I can float the vreh pin even though the data sheet says it should be tied to a voltage so I'm hopeing the same thing will apply for the VDDA pin.
