Register mapping

The table below provides a list of the 8-bit registers embedded in the device and the related

addresses.

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

permanent damage to the device.

The content of the CALIB_0..F registers that are loaded at power-on from device internal

non-volatile memory should never be modified.
