Universal Asynchronous
Receiver/Transmitter
Architecture
PS024314-0308
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. The features of 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.
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 (BRG)
Selectable MULTIPROCESSOR (9-bit) mode with three configurable interrupt schemes
BRG can be configured and used as a basic 16-bit timer
Driver Enable output for external bus transceivers
Figure 10
