Calibration EEPROM Map

Table 9 represents the EEPROM map of the device calibration values. All values are stored as little-endian
4-byte floating point numbers. Every point is 4-bytes long. Access to the data is possible through the
CAL_EEPROM_READ register, which reads 8 bytes starting at the address pointed to by the register input.
