2.3 PCI I/F

Provides 32-bit PCI bus master data transfer

Supports PCI clock with frequency from 0Hz to 33MHz

Supports network operation with PCI system clock from 20MHz to 33MHz

Provides performance meter and PCI bus master latency timer for tuning the threshold to enhance the

performance

Provides burst transmit packet interrupt and transmit/receive early interrupt to reduce host CPU

utilization

As bus master, supports memory-read, memory-read-line, memory-read-multiple, memory-write,

memory-write-and-invalidate command

Supports big or little endian byte ordering

2.4 EEPROM/Boot ROM I/F

Provides writeable Flash ROM and EPROM as boot ROM, up to 128kB

Provides PCI to access boot ROM by byte, word, or double word

Re-writes Flash boot ROM through I/O port by programming register

Provides serial interface for read/write 93C46 EEPROM

Automatically loads device ID, vendor ID, subsystem ID, subsystem vendor ID, Maximum-Latency , and

Minimum-Grand from the 64 byte contents of 93C46 after PCI reset de-asserted

2.5 MAC/Physical

Integrates the complete set of Physical layer 100BASE-TX and 10BASE-T functions

Provides Full-duplex operation in both 100Mbps and 10Mbps modes

Provides Auto-negotiation (NWAY) function of full/half duplex operation for both 10 and 100 Mbps

Provides MLT-3 transceiver with DC restoration for Base-line wander compensation

Provides transmit wave-shaper, receive filters, and adaptive equalizer

Provides MAC and Transceiver (TXCVR) loop-back modes for diagnostic

Built-in Stream Cipher Scrambler/ De-scrambler and 4B/5B encoder/decoder

Supports external transmit transformer with 1.414:1 turn ratio

Supports external receive transformer with 1:1 turn ratio

2.6 LED Display

Provides 2 LED display modes:

3 LED displays for

100Mbps (on) or 10Mbps (off)

Link (Remains on when link ok) or Activity (Blinks at 10Hz when receiving or transmitting collision-free)

FD (Remains on when in Full duplex mode) or when collision detected (Blinks at 20Hz)

4 LED displays for

100 Link (On when 100M link ok)

10 Link (On when 10M link ok)

Activity (Blinks at 10Hz when receiving or transmitting)

FD (Remains on when in Full duplex mode) or when collision detected (Blinks at 20Hz)
