+ * Automatic scale calibration.
+ *
+ * Basic idea:
+ *
+ *   output = (ext field +- 1.1 Ga self-test) * scale factor
+ * 
+ * and consequently:
+ *
+ *   1.1 Ga = (excited - normal) * scale factor
+ *   scale factor = (excited - normal) / 1.1 Ga
+ *
+ *   sxy = (excited - normal) / 766	| for conf reg. B set to 0x60 / Gain = 3
+ *   sz  = (excited - normal) / 713	| for conf reg. B set to 0x60 / Gain = 3
+ *
+ * By subtracting the non-excited measurement the pure 1.1 Ga reading
+ * can be extracted and the sensitivity of all axes can be matched.
+ *
+ * SELF TEST OPERATION
+ * To check the HMC5883L for proper operation, a self test feature in incorporated
+ * in which the sensor offset straps are excited to create a nominal field strength
+ * (bias field) to be measured. To implement self test, the least significant bits
+ * (MS1 and MS0) of configuration register A are changed from 00 to 01 (positive bias)
+ * or 10 (negetive bias), e.g. 0x11 or 0x12.
+ * Then, by placing the mode register into single-measurement mode (0x01),
+ * two data acquisition cycles will be made on each magnetic vector.
+ * The first acquisition will be a set pulse followed shortly by measurement
+ * data of the external field. The second acquisition will have the offset strap
+ * excited (about 10 mA) in the positive bias mode for X, Y, and Z axes to create
+ * about a ±1.1 gauss self test field plus the external field. The first acquisition
+ * values will be subtracted from the second acquisition, and the net measurement
+ * will be placed into the data output registers.
+ * Since self test adds ~1.1 Gauss additional field to the existing field strength,
+ * using a reduced gain setting prevents sensor from being saturated and data registers
+ * overflowed. For example, if the configuration register B is set to 0x60 (Gain=3),
+ * values around +766 LSB (1.16 Ga * 660 LSB/Ga) will be placed in the X and Y data
+ * output registers and around +713 (1.08 Ga * 660 LSB/Ga) will be placed in Z data
+ * output register. To leave the self test mode, change MS1 and MS0 bit of the
+ * configuration register A back to 00 (Normal Measurement Mode), e.g. 0x10.
+ * Using the self test method described above, the user can scale sensor
