Universal Asynchronous Receiver/

Transmitter

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:

• 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

Architecture

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. Figure 10 displays the UART architecture.
