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.

25 MHz crystal/OSC. Input
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.
Request2, The 2nd device will assert this pin low to request the ownership
of the PCI bus.
Grant2, This signal is asserted low to indicate that the central arbiter has
granted ownership of the bus to the 2nd device.
Initialization device select 2, Used as a chip-select during configuration read
and write transactions to the 2nd device.
Chip test pin
ROM Chip Select and Output Enable, This is the chip select signal and
output enable for the Boot PROM.
