Factory calibration
The IC interface is factory calibrated for sensitivity (So) and Zero-g level (Off).
The trimming values are stored inside the device by a non volatile structure. Any time the
device is turned on, the trimming parameters are downloaded into the registers to be
employed during the normal operation. This allows the user to employ the device without
further calibration.
