Calibration EEPROM Map
Table 10 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.
