AI summary

A processor chip includes a logic circuit. The logic circuit is configured to be coupled to an electronic device. A configuration of the logic circuit corresponds to a plurality of candidate configurations. The configuration of the logic circuit is switched among the candidate configurations, and the electronic device associates with the processor chip to implement a function corresponding to the configuration of the logic circuit. When the configuration of the logic circuit is a first configuration and the electronic device executes a first driver program, the function is a first network-connection function. When the configuration of the logic circuit is a second configuration and the electronic device executes a second driver program, the function is a second network-connection function different from the first network-connection function.
