摘要： A configurable universal asynchronous receiver/transmitter (UART) facilitates efforts to upgrade UART functionality in the field and replace older UART devices. In one example embodiment, an integrated circuit includes a universal asynchronous receiver/transmitter configured and arranged to operate in one of a plurality of modes, with each mode being selectable in response to mode-selecting data. The integrated circuit device includes an interface circuit electrically connected to the universal asynchronous receiver/transmitter and adapted to present the mode-selecting data to the universal asynchronous receiver/transmitter. The integrated circuit device also includes a selection circuit adapted to enable the mode-selecting data to pass from the interface circuit to the universal asynchronous receiver/transmitter.
