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.
