Configuration Register B
The configuration register B for setting the device gain. CRB0 through CRB7 indicate bit locations, with CRB denoting the
bits that are in the configuration register. CRB7 denotes the first bit of the data stream. The number in parenthesis
indicates the default value of that bit.
The table below shows nominal gain settings.
