Device and method for performing multi-function using unique port in wireless terminal

摘要

Disclosed is a device and method for performing a multi-function using a unique port in a wireless terminal capable of performing a multi-function using the unique port. The device includes an interface unit for outputting a power signal through a connector inserted into the unique port, and performing data transmission/reception between a specific controller and the connector. A signal generating unit outputs a high-level signal by using the power signal output from the interface unit. A switching unit switches to a specific controller to communicate data with the connector, in order to output the high-level signal. At least two controllers, includes at least two transmission/reception units, for transmitting/receiving data to/from the connector through the switching unit.
