I/O

FUNCTION

1

IN Crystal input with internal loading capacitors and feedback

resistors.

2

OUT Crystal output at 14.318 MHz nominally.

5.2 CPU, PCI Clock Outputs

I/O

FUNCTION

22, 21

OUT Low skew (<250 pS) clock outputs for host frequencies

such as CPU, Chipset and Cache. VDDC is the supply

voltage for these outputs.

4, 5, 6, 7, 8 OUT Low skew (<250 pS) PCI clock outputs.

10

I/O If Mode* =1 (default), then this pin is a PCICLK5 buffered

output of the crystal. If Mode* = 0 , then this pin is

PCI_STOP# input used in power management mode for

synchronously stopping the all CPU clocks.

11

I/O If Mode* = 1 (default), then this pin is a PCICLK6 clock

output. If Mode* = 0 , then this pin is CPU_STOP # and

used in power management mode for synchronously

stopping the all PCI clocks.

FUNCTION

I/O Serial data of I2C 2-wire control interface

IN Serial clock of I2C 2-wire control interface
