For the calibration of the sensor, a special hardware interface to a PC is required. All
calibration and setting bits can be temporarily written into a Random Access Memory
(RAM). This allows the EEPROM to remain untouched during the entire calibration
process, since the number of the EEPROM programming cycles is limited. Therefore,
this temporary setup (using the RAM only) does not stress the EEPROM.
The digital signal processing is completely deterministic. This allows a two-point
calibration in one step without iterations. After measuring the Hall output signal for the
two end points, the signal processing parameters Gain and Offset can be calculated.
