CRB_REG_M (01h)
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 parentheses indicates the default value of that
bit.

Table 62.
MR_REG_M (02h)
The mode register is an 8-bit register from which data can be read or to which data can be
written. This register is used to select the operating mode of the device. MR0 through MR7
indicate bit locations, with MR denoting the bits that are in the mode register. MR7 denotes
CRB7 to CRB5
CRB7 to CRB5 This bit must be cleared for correct operation
