GL850G controls the LED lighting according to the flow defined in section 11.5.3 of Universal Serial Bus
Specification Revision2.0 . Both manual mode and Automatic mode are supported in GL850G. When
GL850G is globally suspended, GL850G will turn off the LED to save power.
GL850G replies to host commands by the default settings in the internal ROM. GL850G also offers the
ability to reply to the host according to the settings in the external EEPROM(93C46). The following table
shows the configuration of 93C46.
