Abstract
An input and/or output pad is dedicated to an integrated circuit comprising a core with input and/or output pins. This pad comprises a pad cell comprising a pad block connected to an input buffer and/or an output buffer and arranged to be connected to one of the core input and/or output pins. The pad also comprises a pad logic module comprising a first and/or a second boundary scan cell, connected to the pad block through the input buffer and/or output buffer and arranged to feed input signals to and/or deliver output signals from the pad block, and control means connected to the first and/or second boundary scan cell(s) and adapted to receive control signals for controlling access to the first and/or second boundary scan cell(s) and feeding the first boundary scan cell with the input signals and/or outputting the output signals delivered by the first boundary scan cell.
