EEPROM contents arrangement
The SN11220ACF supports an external EEPROM93C46to 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.

USB VID and PID The default USB VID of SN11220ACF is 0x0C45. The default PID is composed by the configurations as below {0, 0, 0, 1, 1, 1, 0, 1, 1, 0, 1, 1, 1, RECORD, POWER_BIT, 1}. If pin38 tie to high, RECORD will equal "1". The POWER_BIT is
Sonix Confidential -9Do not copy, reproduce, or distribute without permission 2006 Aug 10, V1.01
Data Sheet USB Audio Controller SN11220ACF
used to indicate that the MaxPower in USB descriptor "1" is 100mA, "0" is 500mA . The VID and PID can be changed by using EEPROM. Word address 0x00 is the VID value. Word address 0x01 is the PID value. The bit1 (POWER_BIT) of the PID value will affect the MaxPower in USB descriptor. It should be noted that forbids the VID and PID values cannot be set to 0x0000 or 0xFFFF. Manufacturer and Product String The default manufacturer string is "GENERIC". It can be changed by programming word 0x02 to 0x09 in EEPROM and set the length of it in word 0x12, bit 4 to 7. Manufacturer string length = manufacturer string # + 1manufacturer string # = 0x0F means manufacturer string length = 16 bytes. There are total of two default product strings in SN11220ACF, depending on the features selected. They are listed in the table below. RECORD 0 1 USB Speaker USB Headset Product String
The product string can be changed by programming words 0x0A to 0x11 in EEPROM and set the length of it in word 0x12, bit 0 to 3. Product string length = product string # + 1product string # = 0x0F means product string length = 16 bytes. Control word 1 The control word 1 is located in word 0x12 of EEPROM. Bit 0 to 7 is the length of USB strings and has been explained in previous paragraphs. Bit 8 is used to set the self-power bit in the USB descriptor. Bit 9 is used to enable remote wake feature in USB. The remote wakeup keys are VOLP/VOLD/MUTEP/MUTER. Bit 10 to 14 is reserved in SN11220ACF. Bit 15 is to enable the left-justify format in I2S mode. Control word 2 The control word 2 is located in word 0x13 of EEPROM. Bit 0 to 7 is the interval of USB HID Report IN. For example, bit 0 to 7 = 0x0A

Data Sheet USB Audio Controller SN11220ACF
means that the interval of USB HID Report IN is 10ms and this is default value. Bit 13 to 15 are reserved for future using and influence no function of SN11220ACF. Bit 12 is used to enable the EEPROM setting for configure the source of CODEC. If bit 12 is "0", PCM configuration is defined by pin PADFUN3~0. PCM configuration bit = 1'b1 PCM configuration bit = 1'b0 Defined by PCM setting3~0 Defined by pin (PADFUN3~0)

VII. HID bytes arrangement
The SN11220ACF is equipped with a special feature to let the host software to communicate with the USB downstream devices via the HID pipe. Using this feature, the system manufacturers can easily upgrade or increase the functions of their product by just updating the software installed on the PC. There are 16 bytes each for HID in and HID out. They will be explained in the paragraphs below separately. To receive the data from two-wire serial port and button/GPIO status from the SN11220ACF, there are two ways. The first is to receive the HID report of the HID pipe regularly. If any button/GPIO value changes or data received from the two-wire serial port, the new values will be sent to the host every HID interval timedefined in word 0x13 bit 0 to 7 and default is 10ms. The second way is to issue a HID class

Data Sheet USB Audio Controller SN11220ACF
request "Get Report" to get the input report. To send data to the USB audio controller, the host software should issue a HID class request "Set Report" to send the output report. There are total of 16 bytes of both output report and input report. The format of them is described as below.

VIII. Two-wire serial port definition
To provide extension capability, SN11220ACF contains a two-wire series bus circuitry as an interface to MCU. The two wire series bus serves as a slave device with bit rate up to 400Kbpsfast mode. MCU can write ten bytes to the SN11220ACF with 8-bit register address 0x38. MCU can also read ten bytes from SN11220ACF with 8-bit register address 0x39. This section just provides simple description of the two-wire series bus. It is compatible with the I2C slave mode. User can get more detail explanation from the I2C specification. The input pin "SCL" is used to get the two wire series bus clock from MCU, and the open-drain output pin "SDA" is used to send or receive serial signal to/from MCU. As shown below, "SDA" should be stable when "SCL" is high, and can have transition only when "SCL" is low.
START and STOP conditions shown below are the exception. Every transaction begins from a START, and ends with a STOP, or another STARTrepeated START.

The figure below demonstrates a typical two-wire serial bus transaction. After every 8 bits sent by the transmitter, the receiver should send one bit low for positive acknowledgement; a STOP or repeated START should follow. The next figure shows more detailed about acknowledgement bit. Note that "SCL" is always driven by the master.

The figure below shows a complete data transfer. After a STRAT, MCU should send 7-bit slave address 7'b0011100 first, and then the 8th bit denotes a read transfer when it's 1 ; or a write transfer when it's 0. Note that address 0x0b is the indicator to notice SN11220ACF to update the data written by MCU to PC via USB HID. Writing any thing to address 0x0b means the SN11220ACF can transfer all the data to PC. Before address 0x0b be written, SN11220ACF will transfer the last data which the last indicator launched.
