Data Sheet
SN11300
3 In 1 USB Audio Controller
Control byte 4:
The control byte 4 is located in byte 0x0D of EEPROM. Bit 0 is external LCM exist
bit. Default value is zero. Set 1 to this bit will disable internal LCM display function.
Bit 1 is external key exist bit. Default value is zero. Set 1 to this bit will disable
internal key function. Bit 2 to 5 is I2C timeout filed, SN11300 can communicate
with external MCU by I2C interface, and this filed indicate SN11300 should wait
how long when I2C interface fail to avoid system enter the dead loop. Bit 6 and Bit7
are reserved, set to 0.
Language ID
The language ID filed indicates the codes representing languages supported by
SN11300. The default value is 0x04, 0x03, 0x09, and 0x04.
USB Manufacturer, Product and Serial string length:
The length of the vendor, product and serial string is user define. They are
sequentially located in byte 0x14 to 0x16 of EEPROM. The only limitation is the sum
of the all string length and API reserved bytes can’t be over EEPROM size.
USB Manufacturer, Product and Serial string:
The USB string entity is start from byte 0x17 of EEPROM. They are sequentially
Manufacturer, Product and Serial string.
API reserved bytes:
The last 16 bytes of EEPROM is reserved for API used.
