Abstract
An interrupt controlling method and apparatus is disclosed. The method and apparatus generates allows a connecting gate to output different signals according to whether charging electric power or communication electric power is supplied to the connector unit of the portable terminal and then outputs them to the power management IC. The power management IC performs a controlling operation in such a way that it can generate only a charging interrupt command if a travel adaptor is connected to the connector unit and generate a communication interrupt when the communication device is coupled to the connector unit.
