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.
