摘要： Disclosed are a method for automatically originating an international call and a mobile communication terminal using the same, such that a function of automatically originating an international call according to movement of a mobile communication terminal between countries is provided. The mobile communication terminal includes a country code detecting unit for informing a country code for a corresponding country by detecting movement of a mobile communication terminal between countries. If the country code detecting unit provides an allowable country code according to the position of the mobile communication terminal, a control unit adds an international dialing code to preset information regarding a call terminating side so as to enable call connection. When the user registers a phone number of a communication counterpart in a phone directory, the user previously registers a country code for a country (in which the counterpart is located) and an area code in addition to the phone number of the counterpart as the information regarding the call terminating side. Accordingly, the user can call the counterpart positioned in another country without additionally inputting an international dialing code and a country code whenever the user originates a call.

摘要： An error detecting circuit for detecting the location of an error is provided. The error detecting circuit has an error data storing unit and an error data collecting unit. The error data storing unit divides a circuit having areas, and outputs a plurality of error signals in response to a plurality of state error signals, a serial chain signal, a lock-enable signal, and a chip error signal, which are enabled when an error occurs in the corresponding area. The serial chain signal reads the plurality of state error signals if the chip goes out of order when an error occurs in the circuit. The lock-enable signal determines whether or not to preserve the plurality of state error signals. In response to the serial chain signal, the error data storing unit enables a confirmation of at least one state error signals stored in the error data storing unit.
