MPU 9150 pinout datasheet vs SDK schematics

Hi

I am currently designing a board for a new sport equipment. We are using the MPU 9150 as the sensor and using the motionfit SDK as a reference design.

When going though all the connections in the motionfit schelatic, i noticed that the pinout of the MPU 9150 is not the same as the datasheet of the chipset.

I understand that the names of the pins are not the same (especially the RESV pin that are labelled in the motionfit schematic) but the connections are not the same.

The most important difference is the pin 15, labelled as GND in the datasheet while labelled as CAD1 in the schematic and connected to 3V. Which document should be trusted ?

Thank you
