Calibration
Start
The Calibration mode is entered by writing a 1 to the Calibration Mode bit. While in the calibration mode the
calibration registers may be accessed, the Capture may be used to capture the real-time value and the Calibration
Start may be set.
When the Calibration Start bit is set the Calibration Status bit will remain set until the calibration process is
complete. Setting the Calibration Reset bit will clear the calculated Offset values.
