Universal Asynchronous Receiver/Transmitter (UART)

Full-duplex asynchronous receiver/transmitter
• Quadruple buffered receiver data register
• Programmable data format:
– 5 to 8 data bits plus parity
– Odd, even, no parity or force parity
– 1, 1.5 or 2 stop bits programmable in 1/16-bit increments
• 16-bit programmable Counter/Timer
• Baud rate for the receiver and transmitter selectable from:
– 22 fixed rates: 50 to 115.2K baud
– Non-standard rates to 115.2 kb
– Non-standard user-defined rate derived from programmable timer/ counter
– External 1X or 16X clock
• Parity, framing, and overrun detection
• False start bit detection
• Line break detection and generation
• Programmable channel mode
– Normal (full-duplex)
– Automatic echo
– Local loopback
– Remote Loopback
• Multi-function programmable 16-bit counter/timer
