UART
Architecture
PS019921-0308
The Universal Asynchronous Receiver/Transmitter (UART) is a full-duplex communica-
tion channel capable of handling asynchronous data transfers. The UART uses a single
8-bit data mode with selectable parity. Features of the UART include:
•
•
•
•
•
•
•
•
•
•
The UART consists of three primary functional blocks: Transmitter, Receiver, and Baud
rate generator. The UART’s transmitter and receiver function independently, but employ
the same baud rate and data format.
