LED0 displays for activity status. This pin will be driven with 5 Hz frequency

when either effective receiving or transmitting is detected.

LED1 displays for link status.

LED2 displays for 100 M link status.

LED3 displays for full-duplex mode.

XTAL25I

25 MHz crystal/OSC. Input

XTAL25O

Crystal feedback output, This output is used in crystal connection only. It

must be left open when X1 is driven with an external 25 MHz oscillator.

Multi-Function Interface

REQB2

Request2, The 2nd device will assert this pin low to request the ownership

of the PCI bus.

GNTB2

Grant2, This signal is asserted low to indicate that the central arbiter has

granted ownership of the bus to the 2nd device.

IDSEL2

Initialization device select 2, Used as a chip-select during configuration read

and write transactions to the 2nd device.

Test And Other Pins

TM0

TM1

Chip test pin

ROM_OE

ROM Chip Select and Output Enable, This is the chip select signal and

output enable for the Boot PROM.
