REG2, REG1, REG0
Indicates a read from or a write to the addressed register.
Used in association with the address bits to determine if a read or write operation is to the data register, offset
register, gain register, or function register.

FUNCTION REGISTER
The Function Register is addressed by setting the three REG bits to 000. The values written to the address bits and the data bits determine
the function addressed. The Functions available through the function register are shown in Table 10 and
