PCI Bus Interface
PCI Outbound Memory Base Address Register
(PCI_MBAP)
This register, shown in
Figure 13-6
, is the PCI memory base address
pointer that is prepended to the EAB address for outgoing PCI memory
transfers. The 5-bit PCI Space Address is prepended to the 27-bit offset
into the PCI memory space window in the ADSP-BF535 processor EAB
space. Write to this register before attempting a read or write to or from
PCI memory space.
PCI Outbound I/O Base Address Register
(PCI_IBAP)
This register, shown in
Figure 13-7
, is the I/O base address pointer.
