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 bq27500/1 during normal operation and additional features when the bq27500/1 is in
different access modes, as described in Table 4-2.
