Three qestions about MotionFX CM0+

Hello wonderfull STM community,

Really enjoying the experience with MotionFX so far, really easy to implement and get working, well done ST! Even on a G0 in CM0+ mode its working well! I'm just woudring three things:

  1. What precaution(s), if any, should be taken when pausing and later resuming the RTOS task that runs MotionFX_CM0P_update()?
  2. What is the refrence point for the quatenion in 6x mode? (to be fair I have not worked much with quatenions before so that might be an uneducated question. They are quite complex after all! (pun intended)) 
  3. Is it normal for data_out.rotation_6x to be near 0 (e-16) during oppration in 6 axis mode? (other values, inlcuding inputs, are changing as expected)

Note that mag is just uninitialized, the values are those of what was already in memory, I should fix that, through this is the first I've noticed it.

Thanks and happy coding!
