Abstract

An electronic device, a logic chip and a communication method of the logic chip are provided. The electronic device includes a connection port, a processor and the logic chip. The connection port is coupled to a peripheral device and the processor is coupled to the connection port. The logic chip has a plurality of interface modes, and includes a first communication interface, a second communication interface and a logic circuit. The first communication interface is coupled to the processor. The second communication interface is coupled to the connection port. The logic circuit is coupled between the first and second communication interfaces and makes the logic chip operate in the interface mode corresponding to the connection port according to a predetermined mode signal. The processor communicates with the peripheral device through the logic chip operating in the interface mode corresponding to the connection port and the connection port.

Description

technical field [0001] The present invention relates to a communication technology, and in particular to an electronic device, a logic chip and a communication method of the logic chip. Background technique [0002] With the advancement of technology, electronic devices need to be connected to various peripheral devices with different communication protocols, such as keyboards, monitors, etc., and thus have various communication interfaces to support these different types of peripheral devices. However, due to different communication interface types, there are many circuit designs between the communication interface of the electronic device and the processor. [0003] figure 1 A schematic block diagram illustrating a communication block between an electronic device and a peripheral device in the prior art. like figure 1 As shown, the electronic device 100 can be coupled to a plurality of peripheral devices 210, 220, 230, 240 with different communication specifications. 2...
