7. SERIAL EEPROM INTERFACE DESCRIPTION AND MODE SETTING
The serial EEPROM (93C46) is optional for some of parameter setting. If SEM_CS = high(short to
VDD3) is used to set the default parameter mode (like default USB VID/PID). And the LED indicator
mode set at SEM_SK and SEM_WSD pins. If the pin SEM_CS is Open and the serial EEPROM is
existent, the parameters should load from the serial EPPROM.
7.1 The Data Format of Serial EEPROM
If the parameter is read from serial EEPROM, the LED indicator mode is set in one byte data stored in
the EEPROM.
Data record in 93C46 for setting:
Only one set of VID, PID, power setting, string descriptor, and LED setting in the 93C46.
