7.3.1.2 Control(): 0x00/0x01

Issuing a Control() command requires a subsequent two-byte subcommand. These additional bytes specify the particular control function desired. The Control() command allows the host to control specific features of the BQ34Z100-G1 during normal operation, and additional features when the BQ34Z100-G1 is in different access modes, as described in Table 7-2.
