OPERATING METHOD OF CONTROLLER FOR SETTING LINK BETWEEN INTERFACES OF ELECTRONIC DEVICES, AND STORAGE DEVICE INCLUDING CONTROLLER

摘要

An operating method includes sensing a connection of the first electronic device to an interface circuit of the second electronic device; receiving an identification code from the first electronic device; and setting a state of the interface circuit as an express linkup state corresponding to the received identification code. The identification code has a value different from values defined and reserved in an interface protocol which defines an operating procedure of the interface circuit. The value of the identification code varies with an attribute of the first electronic device.

1. A method of operating a controller, the method comprising:
sensing, by the controller, a connection of a first electronic device to an interface circuit of a second electronic device, the second electronic device associated with the controller; receiving an identification code from the first electronic device after the connection of the first electronic device is sensed, the identification code having a value different from values defined and reserved in an interface protocol, the interface protocol defining an operating procedure of the interface circuit, the value of the identification code being based on attributes of the first electronic device; and setting a state of the interface circuit as an express linkup state based on the received identification code such that data communication from the second electronic device to the first electronic device is enabled.
