Start Offset Calibration. Starts the proximity offset register calibration
routine. Results are stored in the Proximity Offset Registers (0xC0 – 0xC7).
The CALIB_FINISHED flag is asserted when calibration is complete and an
interrupt (CINT) is asserted if CIEN is set. Calibration can be stopped by
writing a 0 to this field.
