AM2432: Power Related Pins

Hi Team,

My customer had the following concerns regarding power pins. Refer to image below.

1. About the Power Supply Signal Descriptions table and Pin Attributes table of AM243x datasheet.
   In Rev.B datasheet, these tables say Ball A5, A6(ALV package) are VSS.but in Rev.C datasheet, these tables say Ball A5, A6 are not included in VSS group.
   On the other hand, Pin Diagram(Bottom View) - ALV package of both RevB and RevC say A5, A6 are VSS pin.
   Are ball A5 and A6 VSS?.
2. It seems that information on power supply signal VDDSHV0-5 have inconsistency between Rev.B and Rev.C. For examble ball G12, G14 are VDDSHV0 pin acording to Pin diagram(Bottom View)(ALV package) of Rev.C datasheet. but there are no G12, G14 in item VDDSHV0 of Power Supply Signal Description table of Rev.C datasheet. 
3. Why does Rev.c datasheet have 31 balls missing?

Best regards,
