GL852 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 GL852. When GL852
is globally suspended, GL852 will turn off the LED to save power.
GL852 replies to host commands by the default settings in the internal ROM. GL852 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.
