Important notes:
1) Bits 5, 6 and 7 of register addresses 14h do contain critical sensor individual calibration data
which must not be changed or deleted by any means.
In order to properly modify addresses 14h for range and/or bandwidth selection using bits 0, 1,
2, 3 and 4, it is highly recommended to read-out the complete byte, perform bit-slicing and write
back the complete byte with unchanged bits 5, 6 and 7.
Otherwise the reported acceleration data may show incorrect results.
2) Bit 7, bit 5 and bit 4 of register 0Ah should be left at a value of “0”.
