LM3S2965 Microcontroller
13 Universal Asynchronous Receivers/Transmitters
(UARTs)
The Stellaris^® Universal Asynchronous Receiver/Transmitter (UART) provides fully programmable,
16C550-type serial interface characteristics. The LM3S2965 controller is equipped with three 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
■ IrDA serial-IR (SIR) encoder/decoder providing:
– Programmable use of IrDA Serial InfraRed (SIR) or UART input/output
– Support of IrDA SIR encoder/decoder functions for data rates up to 115.2 Kbps half-duplex
– Support of normal 3/16 and low-power (1.41-2.23 μs) bit durations
– Programmable internal clock generator enabling division of reference clock by 1 to 256 for
low-power mode bit duration
