Compass calibration Issue

Hello All,


   I am using Three-Axis Digital Magnetometer (MAG3110) and 3-Axis Digital Accelerometer (MMA8451Q) for my COMPASS ,

As per freescale provided algorithm, compass calibration data ( hard and soft iron) is not stored anywhere and hence requires recalibration for each power on .

Is their in way to store the calibrated values and apply these values on successive power ON? If it is possible, what values should be stored ?
