Control( ): 0x00/0x01
Issuing a Control( ) command requires a subsequent 2-byte subcommand. These additional bytes specify the
particular control function desired. The Control( ) command allows the system to control specific features of the
fuel gauge during normal operation and additional features when the device is in different access modes, as
described in Table 2. Additional details are found in the bq27510-G3 Technical Reference Manual.
