Pin behavior of BF526 at hibernate state

In my application , the DSP is supposed to enter the hibernate state to save power. In the datasheet, appears a "mysterious" sentence stating that


"Since Vddext and Vddmem can still by applied in this mode,all of  the external pins  three-state,unless otherwise specified". Can someone please explain this ?. Does it mean that I can set the actual value of each pin, and if I don't, then it will three-state ?. If so, where does this specification takes place.
