6.13 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.
