Data Sheet  
SN11300  
3 In 1 USB Audio Controller  
VII. HID bytes arrangement  
The SN11300 is equipped with a special feature to let the host software to  
communicate with the USB downstream devices via the HID pipes. 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. The detail is  
described in the HID application note.  
VIII. Two-wire serial port definition  
To provide extension capability, SN11300 contains a two wire series bus circuitry as  
an interface to external MCU. The two wire series bus serves as a slave device with  
bit rate up to 400Kbpsfast mode. External MCU can write 16 bytes to the  
SN11300 with 7-bit register address 0x5A. MCU can also read 16 bytes from  
SN11300 with 7-bit register address 0x59. The detail is described in the EXT-MCU  
application note and EXT-MCU programming guide.
