MPU-6000 Sample Time

If I run an MPU-6000 in a system where I generate an FSYNC pulse to initiate a new set of data, how long does it take for the 6 axis of data to become available in the user facing registers after asserting FSYNC?

And is this FSYNC initiated sample time independent of the rate that I choose to run the gyros and accelerometers at?

Thanks,

David

FSYNC logic state will be captured along with the raw sensor data. If using eMPL, this is at 200 Hz, or may vary if you are controlling the data rate. When utilized, the LSB of one of the sensor registers (typically TEMP) will track the state of the FSYNC pin, so you can analyze the orientation during the frame capture. The FSYNC feature is typcally used for image stabilization.
