It detects the feedback signal that external equipment is output on USB socket 40, then carries out charge protocol with the external equipment and interact with true
Fixed external equipment, for example determine whether the external equipment is charging equipment or is non-charging equipment, and to first processor
10, which send external equipment, accesses notification message.
It is further alternative, in one embodiment of binary channels mobile terminal of multiplexing USB port of the present invention, in the first processing
When device 10, second processor 20 carry out double-channel data merging treatment, first processor 10 establishes what USB was connect with external equipment
Process is as follows:
(1) when first processor 10, second processor 20 carry out communication and power management chip 30 detects USB socket 40
When the external equipment of upper access is computer, power management chip 30 sends the notice that computer accesses to first processor 10 and disappears
Breath, the form of the notification message are unlimited；
(2) first processor 10 upon receiving the notification message, control switch chip 502 be connected to first processor 10 with
The differential signal wire pin of USB socket 40；And the load setting voltage on itself differential signal wire pin, to generate difference letter
Number and by switch chip 502 connection output to USB socket 40 differential signal wire pin；
(3) first processor 10 and computer carry out enumeration process, connect and are led to for establishing USB with computer
Letter.In the present embodiment, computer is initiated as USB from equipment, therefore by computer as USB main equipment, first processor 10
