Fig 6-17 Function Block Diagram
In Universal Asynchronous Receiver Transmitter (UART), each transmitted or received
character is individually synchronized by framing it with a start bit and stop bit.
Full duplex data transfer is possible since the UART has independent transmit and
receive sections. Double buffering for both sections allows the UART to be
programmed for continuous data transfer.
