64-bit implementation
When inserted into a slot, a 64-bit PCI card tests whether that slot is 64-bit or 32-bit. If REQ64 is low when
PCI_RST is deasserted, that signals the card that the slot is 64-bit; otherwise, the slot is 32-bit. The HPC3130A
provides a mechanism to notify the PCI card it is connected to a 64-bit PCI slot. The mechanism uses REQ64ON
and REQ64ON as CBT switch enables and SLOTREQ64 as the slot specific REQ64 signal. As depicted in
figures 12 and 13, REQ64ON enables the CBT switch that routes SLOTREQ64 to the slot, and REQ64ON
enables the CBT switch that routes SYSTEMREQ64 to the slot. SYSTEMREQ64 will always be routed to the
slot except when the slot is disconnected from the bus or during a connection sequence. It is very important
during a connection sequence that the software clears bit 3 in the hot plug control registerto drive SLOTREQ64
low. The HPC3130A will deassert SLOTREQ64 during the automatic connection sequence.
In a 32-bit PCI bus implementation, the SLOTREQ64, REQ64ON, and REQ64ON outputs are not connected.
