Universal Asynchronous Receivers/Transmitters
(UARTs)
The Universal Asynchronous Receivers/Transmitters (UARTs) provide fully programmable,
16C550-type serial interface characteristics. The LM3S316 controller is equipped with two UART
modules.
Each UART has the following features:
Separate transmit and receive FIFOs
Programmable FIFO length, including 1-byte deep operation providing conventional
double-buffered interface
FIFO trigger levels of 1/8, 1/4, 1/2, 3/4, and 7/8
Programmable baud-rate generator allowing rates up to 460.8 Kbps
Standard asynchronous communication bits for start, stop and parity
False start bit detection
Line-break generation and detection
Fully programmable serial interface characteristics:
–
–
–
5, 6, 7, or 8 data bits
Even, odd, stick, or no-parity bit generation/detection
1 or 2 stop bit generation
