Universal Asynchronous Receivers/Transmitters (UARTs)
11 Universal Asynchronous Receivers/Transmitters
(UARTs)
Each Stellaris^® Universal Asynchronous Receiver/Transmitter (UART) has the following features:
■ Two fully programmable 16C550-type UARTs
■ Separate 16x8 transmit (TX) and receive (RX) FIFOs to reduce CPU interrupt service loading
■ Programmable baud-rate generator allowing speeds up to 3.125 Mbps
■ 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
■ Standard asynchronous communication bits for start, stop, and parity
■ 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
