ABSTRACT:
A method of setting the polarity of a digital signal coming from a first integrated circuit, said digital signal being representative of data generated within the integrated circuit and requiring application to an input of a second integrated circuit that requires a predetermined polarity. The method comprises storing the required polarity externally to said first integrated circuit at its digital signal output, an acquisition sequence for acquiring the stored polarity while the data is inactive, and an application sequence for applying the acquired polarity to the information when active in order to generate on an output of said first integrated circuit the digital signal for application to the input of said second integrated circuit. The method is applicable in digital systems that include integrated circuits that may come from different sources.
