From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx> Every other register related to raw value on the datasheet is described as correpsonding to the 12MSB of the actual data registers + the bottom 4 bits are 0. So lets treat this as what it actually is, which is a 12 bit value. Note that we will have to be a little careful to compensate for the offset and scale values.
