FIELD: information technology.
SUBSTANCE: interfacing circuit contains a power management integrating circuit (PMIC), a Universal Serial Bus (USB) controller, an integrated circuit IC and a USB port in which the ID1 contact of the PMIC circuit is connected to the ID2 contact of the IC and the CC1 contact of the IC is connected to the CC2 contact in USB port; the information contact in the USB controller is connected to the information contact of the USB port via the IC; in the master/slave switching state, the IC disconnects ID2 from the CC1 and sets the ID2 to a high level and the CC1 to a low level; in the slave/master switch state, the IC disconnects ID2 from CC1, and sets ID2 to a low level and CC1 to a high level; in the non-diversion state, the IC is in a state where the ID2 is connected to the CC1.
EFFECT: thanks to the use of the coupling scheme, the necessary information interaction between the terminals is achieved by switching the state of the terminals when connected to the connecting line.
