Pins 15 and 17 of MPU9150

Hello,
There is some discontinuity between the REV B Board Schematic and the MPU9150 Datasheet.
The MPU9150 Datasheet states to tie 15 and 17 to ground, but in the board layout of the MotionFit SDK, 15/17 are labelled CAD1/CAD0 with 15 being tied to the positive rail.
Please advise.
