Used to store flag setup information at the SYSTEM communication end point. When bit0 of flag data (No. 2
byte of option data) is 1 in opening the SYSTEM communication end point from the host interface, this setup is
enabled. When bit0 is 0, this setup is disabled.
Also, this setting is used as an open parameter even when the
serial emulation mode is enabled.
