Registers marked as Reserved must not be changed. Writing to those registers may cause permanent damage to

the device.

To guarantee the proper behavior of the device, all register addresses not listed in the above table must not be

accessed and the content stored in those registers must not be changed.

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.
