PCI_M66EN D49 Module input signal indicates whether an off-module PCI device is capable of 66MHz operation. Pulled to
GND by Carrier Board device or by Slot Card if the devices are NOT capable of 66MHz operation.
If the module is not capable of supporting 66MHz PCI operation, this input may be a no-connect on the
module.
If the module is capable of supporting 66MHz PCI operation, and if this input is held low by the carrier
board, the module PCI interface shall operate at 33MHz.
