Any difference those VDDS pins with others?

Other Parts Discussed in Thread: AM3715

Hi,

The following pins are separately listed as "VDDS" in AM3715's datasheet: AG20, AG21 and H28. However there is another group of pins also listed as "VDDS" that is explained as "1.8V power for standard IOs". Those pins include AD3/AD4/W4/AF8/AE8/AF16/AE16/AF23/AE23/F25/F26/AG27. What is the difference between the two groups of "VDDS"? Can they be tide together? Or must be separately treated? Any voltage difference on them?

Please advise.

    Anything labeled VDDS can be treated the same and tied together.  They are listed separately because other versions of the device would have added features which would require separate voltage rails.
