FEATURES (continued)

§ 10/100 Ethernet MAC

- Flexible IEEE 802.3 MII (10/100Mbps) and

ENDEC (10Mbps) interfaces allow selection

of PHY

- Low-power operation

- Ultra-low-power sleep mode with Magic

Packet™ and wake-up frame detection

- 8kB on-chip Tx/Rx packet data memory

with buffer control unit reduces load on

CPU

- Half- or full-duplex operation with flow

control

- Multicast/broadcast address filtering with

VLAN support

§ Full-Function CAN 2.0B Controller

- 15 message centers

- Supports standard (11-bit) and extended

(29-bit) identifiers and global masks

- Media byte filtering to support

DeviceNet™, SDS, and higher layer CAN

protocols

- Auto-baud mode and SIESTA low-power

mode

§ Integrated Primary System Logic

- 16 total interrupt sources with 6 external

- Four 16-bit timer/counters

- 2X/4X clock multiplier reduces

electromagnetic interference (EMI)

- Programmable watchdog timer

- Oscillator-fail detection

- Programmable IrDA clock
