4.5 PCI Expansion Slots
The evaluation platform has four PCI 32-bit/33-MHz expansion slots (J4D1, J4D2, J4E1, J4F1)
and two PCI 64-bit/66-MHz expansion slots (J4A1, J4B1).
4.6 PCI Device Mapping
On the evaluation platform the PCI devices are mapped to PCI device numbers by connecting an
address line to the IDSEL signal of each PCI device. Table 4-1 shows the mapping of PCI devices.
4.7 PCI64 Device Mapping
Table 4-2 shows the mapping of 64-bit/66-MHz PCI devices off of the P64H. The P64H does not
use PCI device numbers; they are dynamically assigned.
