Register mapping
The table given below provides a listing of the 8 bit registers embedded in the device and
the related addresses:
Table 15.
Registers marked as Reserved must not be changed. The writing to those registers may
cause permanent damages to the device.
The content of the registers that are loaded at boot should not be changed. They contain the
factory calibration values. Their content is automatically restored when the device is
powered-up.
