METHOD FOR DETERMINING A CONDITION OF PIN CONNECTION OF THE INTEGRATED CIRCUIT AND INTEGRATED CIRCUIT THEREOF

摘要

An integrated circuit includes a sensing output terminal, a driver, a first sensing input terminal, a second sensing input terminal and a sensor. The driver is used to transmit a sensing test signal through the sensing output terminal. The first sensing input terminal is coupled to the sensing output terminal through a first external circuit for receiving the sensing test signal. The second sensing input terminal is coupled to the sensing output terminal through a second external circuit for receiving the sensing test signal. The sensor is used to compare the sensing test signals received by the first sensing input terminal and the second sensing input terminal with a clock signal respectively to generate a first comparison result and a second comparison result.
