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 bq27505 during normal operation and additional features when the bq27505 is in different
access modes, as described in
the particular control function desired. The Control( ) command allows the system to control specific
features of the bq27505 during normal operation and additional features when the bq27505 is in different
access modes, as described in
Table 4-2. Control( ) Subcommands
