LM3S6422 Datasheet, PDF (34/609 Pages) Texas Instruments – Stellaris® LM3S6422 Microcontroller

Architectural Overview
• 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
■ Synchronous Serial Interface (SSI)
– 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
■ 10/100 Ethernet Controller
– Conforms to the IEEE 802.3-2002 specification
• 10BASE-T/100BASE-TX IEEE-802.3 compliant. Requires only a dual 1:1 isolation
transformer interface to the line
• 10BASE-T/100BASE-TX ENDEC, 100BASE-TX scrambler/descrambler
• Full-featured auto-negotiation
– Multiple operational modes
• Full- and half-duplex 100 Mbps
• Full- and half-duplex 10 Mbps
• Power-saving and power-down modes
– Highly configurable
• Programmable MAC address
• LED activity selection
• Promiscuous mode support
• CRC error-rejection control
