Abstract
A method for using pins in different mode during different time is provided. The method is able to make at least one pin of a SOC be used in a first interface mode or a second interface mode during different time; wherein the SOC comprises a first interface circuit, a first pin, a second interface circuit, and a second pin; the first interface circuit comprises a first bidirectional PAD unit, a first signal interface unit of the first interface mode and a interface unit of the second interface mode; the second interface circuit comprises a second bidirectional PAD unit, a second signal interface unit of the first interface mode. The method comprises: selecting the output of the first signal interface unit or the output of the interface unit of the second interface mode to be connected with the first pin through the first bidirectional PAD unit during different time.
