Universal Asynchronous Receivers/Transmitters (UARTs)
11 Universal Asynchronous Receivers/Transmitters
(UARTs)
Each Stellaris® Universal Asynchronous Receiver/Transmitter (UART) has the following features:
â Three fully programmable 16C550-type UARTs with IrDA support
â Separate 16x8 transmit (TX) and receive (RX) FIFOs to reduce CPU interrupt service loading
â Programmable baud-rate generator allowing speeds up to 3.125 Mbps
â Programmable FIFO length, including 1-byte deep operation providing conventional
double-buffered interface
â FIFO trigger levels of 1/8, 1/4, 1/2, 3/4, and 7/8
â Standard asynchronous communication bits for start, stop, and parity
â Line-break generation and detection
â Fully programmable serial interface characteristics
â 5, 6, 7, or 8 data bits
â Even, odd, stick, or no-parity bit generation/detection
â 1 or 2 stop bit generation
â IrDA serial-IR (SIR) encoder/decoder providing
â Programmable use of IrDA Serial Infrared (SIR) or UART input/output
â Support of IrDA SIR encoder/decoder functions for data rates up to 115.2 Kbps half-duplex
â Support of normal 3/16 and low-power (1.41-2.23 μs) bit durations
â Programmable internal clock generator enabling division of reference clock by 1 to 256 for
low-power mode bit duration
