AI Technical Summary

Technical Problem

Different devices may support different interface protocols, leading to compatibility issues. Existing technologies also experience increased power consumption and difficulty in achieving low power consumption when switching protocols.

Method used

Design an interface circuit that includes first and second communication circuits and a switching circuit. The switching circuit responds to indication signals from external devices to enable or disable the corresponding communication circuit, thereby enabling flexible switching of protocols and reducing power consumption.

Benefits of technology

This improves the device's compatibility with different interface protocols and ensures that only one communication circuit is enabled at a time, thus reducing the power consumption of the interface circuit.
