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. ADDRESS* CONTENT DESCRIPTION 0 iVender / Device Desc, Low-byte.

One byte of data 00 between each character should not write in the 93C46, the data 00 may be filled in the unused content if the number of characters is less than 45. 58~65 Reserve Reserve 66~81 UFI response data (Product Identification). 16 bytes Product Identification of UFI inquiry data, independent of MS interface or SD/MMC interface. The order should be reverse 7.2 LED Indicator and Mode Setting (when SEM_CS = High) The LED driver outputs are all active low, and use 5V VDD for the LED power. It should avoid the internal regulator to drive LEDs. USB_LEDN, MS_ALEDN and SD/MMC_ALEDN can be use in two LED indicate mode or three LED indicate mode. If SEM_CS short to VDD3 is used to set the default parameter mode, the LED indicate mode also set at SEM_SK and SEM_WSD pins during reset. SEM_SK = Low (open) is 3_LED mode, SEM_SK = High(short to VDD3) is 2_LED mode. The SEM_WSD is effective in 3_LED mode, ALED will not flash when SEM_WSD = Low (open) ALED will flash when SEM_WSD = High (short to VDD3).
