VREFHI pin on TMS320F28062

Other Parts Discussed in Thread: TMS320F28062

In a TMS320F28062 design where the internal voltage reference is to be used, is there guidance on how to connect the VREFHI pin? I have seen the requirement that VREFLO be tied to ground, but nothing explicit regarding VREFHI. Should VREFHI be tied to an external +3.3V even if not used as the reference? Does it matter? My apologies if I just missed any guidance in the docs...
