In the embodiment of the present invention, this electronic equipment can also comprise at least one bus extender (GeneralPurpose Input Output, be called for short GPIO), this at least one GPIO is corresponding with at least one connecting interface described to be connected, for for providing voltage control signal with the grid of the metal-oxide-semiconductor in described at least two transmission circuits.
Optionally, in the embodiment of the present invention, in these at least two transmission circuits, this circuit controller can be respectively arranged with.Concrete, when this circuit controller is metal-oxide-semiconductor, the grid of this metal-oxide-semiconductor can be connected with at least one GPIO place circuit described, drain electrode can be connected with described at least two transmission circuits, and source electrode can be and include the grounding circuit configuring resistance and be connected, and when connecting interface is in enable, namely when at least two transmission circuits normally work, the first voltage is there is between the source electrode of metal-oxide-semiconductor and grid, this first voltage can be the operating voltage for stable metal-oxide-semiconductor, opens or closes so that control metal-oxide-semiconductor.
In addition, the resistance value of the configuration resistance in source circuit can adjust under the voltage signal of GPIO, to realize the adjustment of the electric current to metal-oxide-semiconductor.Namely this configuration resistance can be swept resistance, during as sent voltage high signal at GPIO, can be by the resistance value of configuration resistance is tuned up increasing circuit voltage.
