CM6206
High Integrated USB Audio I/O Controller
CM6206 supports four-wire serial EEPROM interface. When an external serial EEPROM is detected, Vendor ID
and Product ID reported within Device Descriptor will be derived from the content of serial EEPROM. The
organization of serial EEPROM is shown below:
Address = 0
Address = 1
Address = 2
Address = 3
Address = 4
Address = 5
Address = 6
Address = 7
Address = 8
Address = 9
Address = 10
Address = 11
Address = 12
Address = 13
Address = 14
Address = 15
Address = 16
Address = 17
Address = 18
Address = 19
Address = 20
Address = 21
Address = 22
Address = 23
Address = 24
Address = 25
Address = 26
Address = 27
Address = 28
Address = 29
Address = 30
Address = 31
Address = 63
Users can program serial EEPROM via HID interface, as described in the former section. The first word is a
magic code. Only when it matches, CM6206 will regard the serial EEPROM valid.
