Abstract: An input/output module electrically coupled between a control circuit and an input/output pin is provided. The input/output module includes a pre-driver and a post-driver. The pre-driver is electrically coupled to the control circuit, and the post-driver is electrically coupled between the pre-driver and the input/output pin. The pre-driver generates a pull-up selection signal and a pull-down selection signal according to an input signal and an enable signal generated by the control circuit. The post-driver sets a voltage level of the input/output pin according to the pull-up and pull-down selection signals. When the enable signal is at a first logic level, the input/output pin has a high impedance. When the enable signal is at a second logic level, the voltage level of the input/output pin changes with a logic level of the input signal, wherein the first logic level and the second logic level are inverted.
