Table 15 provides a listing of the 8-bit registers embedded in the device and the related

addresses.

Registers marked as Reserved must not be changed as they contain the factory calibration

values. Their content is automatically restored when the device is powered up. Writing to

those registers may change calibration data and thus lead to improper functioning of the

device.
