Multiple-byte write
The FXLS8471Q automatically increments the register address write pointer after a write command is received. Therefore, after
following the steps of a single-byte write, multiple bytes of data can be written to sequential registers after each FXLS8471Q
acknowledgment (ACK) is received.
