Factory calibration
The IC interface is factory calibrated for sensitivity (LA_So, M_GN), Zero-g level (LA_TyOff)
and Zero-gauss level (M_TyOff).
The trim values are stored inside the device in nonvolatile memory. Anytime the device is
turned on, the trim parameters are downloaded into the registers to be used during active
operation. This allows using the device without further calibration.
