OEM Pulldown: It is renamed from PCI_REF and is not required on the module.
PCI Clock In: PCLK is an input to the module from the CKDM66-M clock source and is
one of the system’s PCI clocks. This clock is used by all of the 82443DX Host Bridge
logic in the PCI clock domain. This clock is stopped when the PIIX4E/M PCI_STP#
signal is asserted and/or during all suspend states.
Host Clock In: These clocks are inputs to the module from the CKDM66-M clock source
and are used by the processor and the 82443DX Host Bridge system controller. This
clock is stopped when the PIIX4E/M CPU_STP# signal is asserted and/or during all
suspend states.
Suspend Clock : This signal is not used on the module.
Frequency Status: This signal provides the status of the host clock frequency to the
system electronics. These signals are static and are pulled either low or high to the
V_3S voltage supply through a 10-K resistor. This module is designed for the 66-MHz
strapping option shown below.
Clock Voltage Select: Provides status to the system electronics about the voltage level
at which the CKDM66-M clock generator should be operating. This signal is pulled low
by module.
