Abstract:
An arrangement of integrated circuits, comprising:a reconfigurable integrated circuit including a universal asynchronous receiver/transmitter that is configured and arranged to operate in one of a plurality of data communication modes and including a register adapted to store data for temporary use, each data communication mode being selectable in response to mode-selecting data code; an interface circuit electrically connected to the reconfigurable integrated circuit and adapted to present the mode-selecting data code to the reconfigurable integrated circuit; and a selection circuit adapted to enable the mode-selecting data to be passed from the interface circuit to the reconfigurable integrated circuit, the selection circuit adapted to detect when a series of data writes to the register corresponds to the mode-selecting data code and, in response, reconfiguring the integrated circuit to operate in one of the plurality of data communication modes.
