:: If you can find a reason for tying the resistors to ground via a :: resistor :: from the datasheet specs, then you've got my attention. :: Otherwise, this is :: likely mere superstition by whoever wrote that document I don't have it to hand at the moment, but I do recall uChip produced a low power consumption application note that required all unused pins to be tied to a supply node, and IIRC correctly, there was a power consumption difference between tying high and tying low, don't think resistors were mentioned though.
