The universal asynchronous receiver/transmitter (UART) is a full-duplex communication
channel capable of handling asynchronous data transfers. The two UARTs use a single
8-bit data mode with selectable parity. Features of the UARTs include:
•
•
•
•
•
•
•
•
•
The UARTs consist of three primary functional blocks: transmitter, receiver, and Baud
Rate Generator. The UART transmitter and receiver function independently, but employ
the same baud rate and data format.
