Power-saving and power-down modes
Master or slave operation
Programmable clock bit rate and prescale
Separate transmit and receive FIFOs, 16 bits wide, 8 locations deep
Programmable interface operation for Freescale SPI, MICROWIRE, or Texas Instruments
synchronous serial interfaces
Programmable data frame size from 4 to 16 bits
Internal loopback test mode for diagnostic/debug testing
Two fully programmable 16C550-type UARTs with IrDA support
Separate 16x8 transmit (TX) and 16x12 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
False-start-bit detection
Line-break generation and detection
Single- and differential-input configurations
Four 10-bit channels (inputs) when used as single-ended inputs
Sample rate of one million samples/second
Flexible, configurable analog-to-digital conversion
Four programmable sample conversion sequences from one to eight entries long, with
corresponding conversion result FIFOs
Each sequence triggered by software or internal event (timers, analog comparators, or GPIO)
On-chip temperature sensor
Three independent integrated analog comparators
