Universal Asynchronous Receivers/Transmitters
(UARTs)
The Stellaris
16C550-type serial interface characteristics. The LM3S1911 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 3.125 Mbps
Standard asynchronous communication bits for start, stop, and parity
False start bit detection
Line-break generation and detection
Fully programmable serial interface characteristics:
–
–
–
IrDA serial-IR (SIR) encoder/decoder providing:
–
–
–
–
5, 6, 7, or 8 data bits
Even, odd, stick, or no-parity bit generation/detection
1 or 2 stop bit generation
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
