7.3 EEPROM Configuration
A 9346/93C46 type serial EEPROM can be used to store customized USB device configuration data. These
configuration data will be read by W6694A after power on or reset, and sent to the USB host during enumeration. If
EEPROM is not presented, or the first 16 bits in EEPROM is FFFFh, the default value in W6694A will be sent to the USB
host instead.
