Data calibration registers

The 2’s complement offset correction registers values are used to realign the Zero-g position of the X, Y, and Z-axis after the

device is mounted on a board. The resolution of the offset registers is 1.96 mg/LSB. The 2’s complement 8-bit value would result

in an offset compensation range ±250 mg for each axis. 0x2F: OFF_X, Offset Correction X Register.
