Notes (Table 3-3):
1.
Shaded areas not used by APCe8650A carrier.
2.
The board will return “0” for all addresses that are not used.
The APCe8650 base addresses are determined through the PCI Configuration
Registers. The addresses given in the memory map are relative to the base
addresses PCIBar2 of the APCe8650 carrier as shown in Table 3-2. The
addresses within each IP’s own space are specific to that IP module. Refer to
the IP module’s User Manual for information relating to the IP specific
addressing.
The Carrier registers, IP Identification (ID) spaces, IP Input/Output (IO), IP
Interrupt spaces, and Memory (MEM) spaces are accessible via the PCI bus
space as given in Table 3-3. A 32-bit PCI bus access will result in two 16-bit
accesses to the IP module. A 16-bit or 8-bit PCI bus access results in a single
16-bit or 8-bit access to the IP module respectively.
