4.1.1.1
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-J5 during normal operation and additional features when the bq27505-J5 is in
different access modes, as described in Table 4-2.
