It is connected with port SBU2；Another part data-in port (" Right/ right channel " and port in 3.5mm audio interface
" Left/ L channel ") it is connected with the port D- in USB type C plug interface A with port D+.In third data-interface
Port VBUS is connected with the port VBUS in USB type C plug interface A.Port in Fig. 7, in third data-interface
ID and port GND ground connection.
Specifically, it is assumed that the first data-interface has been connected to terminal device.When 3.5mm audio interface has audio output apparatus
When insertion, port " insertion detection 1 " is connected with " insertion detection 2 ", at this point, port " insertion detection 1 " becomes high level, due to
Port CC is connected with VCONN with " insertion detection 1 ", and therefore, port CC and VCONN become high level.When terminal device detects
After becoming high level to port CC and VCONN, determine that the second data-interface has audio output apparatus access, at this point, can
Pass through the data of port D- and D+ transfer audio files to audio output apparatus.It should be noted that if audio output apparatus
Mike is installed, it can user is inputted by the data-in port MIC/AGND and AGND/MIC in the second data-interface
The data of audio file be transmitted to terminal device.It, can also be in third data if user is intended for terminal device charging
Interface connects a charging equipment, so that charging equipment is terminal device charging.
