Universal Asynchronous
Receiver/Transmitter
Architecture
PS022825-0908
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 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.
Baud rate generator (BRG) can be configured and used as a basic 16-bit timer.
Driver enable (DE) output for external bus transceivers.
Figure 10
