Members
BaseAddress
Physical base addresses that are assigned
by the PCI BIOS.
VirtAddress
Virtual address of device. As
necessary, enter the return value
from
xpcReserveMemoryRegion.See
“Description” on page 9-3 for details.
Length
Length of each region. This value contains
the number of bytes that the board segment
responds to during the configuration space
read. This value might be larger than the
space required by the registers as specified
