$0F: “Who Am I” Value (Read only: Optional)
$10: Offset Drift X LSB (Read/Write)
The following Offset Drift Registers are used for setting and storing the offset calibrations to eliminate the 0g offset. Please refer
to Freescale application note AN3745 for detailed instructions on the process to set and store the calibration values.
Signed byte data (2’s complement): User level offset trim value for X-axis
*Bit weight is for 8g 10-bit data output. Typical value for reference only. Variation is specified in “Electrical Characteristics” section.
