Serial data of I
Serial clock of I
such as CPU, Chipset and Cache. V
voltage for these outputs.
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.
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.
