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

bq27530-G1 during normal operation and additional features when the device is in different access modes, as

described in Table 3. Additional details are found in the bq27530-G1 Technical Reference Manual.
