EEPROM contents arrangement

The SN11220ACF supports an external EEPROM（93C46）to be installed for the

system manufacturers to customize the USB VID, PID and the vendor/product strings

being displayed in the OS to differentiate their own products with the others. The

maximum length of the vendor and product string is 16 ASCII characters each. Some

of the features supported by the chip can also be programmed through setting proper

values in the EEPROM. The table below shows the format of the EEPROM. The

detail is described in the following sub-section.
