Universal Asynchronous
Receiver/Transmitter
Architecture
PS022517-0508
The Universal Asynchronous Receiver/Transmitter (UART) is a full-duplex
communication 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 functions independently, but use
the same baud rate and data format.
8-bit asynchronous data transfer
Selectable even- and odd-parity generation and checking
Option of one or two STOP bits
Separate transmit and receive interrupts
Framing, parity, overrun, and break detection
Separate transmit and receive enables
16-bit Baud Rate Generator
Selectable Multiprocessor (9-bit) mode with three configurable interrupt schemes
BRG timer mode
Driver Enable output for external bus transceivers
Figure11
on page 90 displays the UART architecture.
