SLOTREQ64
The SLOTREQ64 signal must be driven by the HPC3130 during reset of a hot-plug slot. The REQ64 signal must
also be driven by the system PCI bus. This requirement can be implemented using the HPC3130 and the
CBT3306 switch or the CBT3257 switch, as shown in Figures 12 and 13. The PCI REQ64 signal must not pass
through the PCI bus CBT switch controlled by BUSON for this implementation. In a 32-bit PCI bus
implementation, the SLOTREQ64, REQ64ON and RFQ64ON outputs are not connected to any device.
