Directs the device to calculate the offsets for each axis (accounting for any error in
measurements). For maximum resolution, the calibration is done with a dynamic range of
8g and a sample rate of 1.563 Hz.

usable value, because running Auto Calibrate sets the device to the 1.563 Hz
Sample Rate (a frequency at which the tilt application cannot function).
Normal operation.
The device gives more accurate readings, but draws more
current.
The device draws less current than Normal mode does, but at
the expense of accuracy.
The device draws more current than Normal mode does, but less
current than Low Power mode does, and reduces noise.
