A method for configuring IO pads, the method includes determining a current configuration of multiple IO pads of an integrated circuit and whereas the method is characterized by generating multiple boundary scan register words that comprise Configuration information; and repeating the stage of serially writing a certain boundary scan register word to a boundary scan register and outputting the boundary scan register word to multiple IO pad control circuits. A device that includes a core, connected to a boundary scan register, a TAP controller and multiple IO pad circuits, the device is characterized by including a control circuit adapted to determine a current configuration of the IO pads, to generate multiple boundary scan register words that comprise configuration information; and to control a repetition of: writing a certain boundary scan register word to the boundary scan register and outputting the boundary scan register word to multiple IO pad control circuits.
