e) Sensitivity temperature drift adjustment (EEPROM name: STP, STN)

The sensitivity temperature drift for the pressure sensor is adjusted, including the AK8999A internal error.

After performing the span voltage adjustment at 25ºC, use the EEPROM's sensitivity temperature drift

coefficients for adjustment so that the absolute values of the AK8999A's coefficient are matched to

those of the sensor's coefficient.
