Where is the feCompassWin8( ... ) documentation??

Good morning

I am recursing the software for the data fusion. I need a good understanding of the function feCompassWin8( ... ) and the similar for other reference systems.

Is there a presentation of the algorithm in the freescale docs?. Or supply me a reference for this function

Thank You

In my understanding there is a fusion of the information of the compass, since the magnetic field lies always on a vertical plan. But the specific mathematical solution shold be outlined.
