Structure members

usSocket

Low bite inidicates the socket, high bite indicates the function.

usAttributes

The bits are defined as:

bit 0

Determines the type of memory being requested. If the bit is set to 1, I/O address space is being requested. Otherwise the request is for memory window address space.

bit 1

set (1) = attribute memory, 16 bit cards only

bit 2

set (1) = enabled, reset (0) = disabled

bit 3

reset (0) = 8 bit data path, set (1) = 16 bit data path

bit 4

set (1) = paged memory

bit 5

set (1) = shared (not for CardBus)

bit 6

set (1) = first shared (not for CardBus)

bit 7

set (1) = only binding specic memory windows

bit 8

set (1) = card offsets are window sized

bit 9

set (1) = 32 bit data path width, CardBus only

bit 10

reserved, reset to 0

bit 12-11

0 0

neither prefetchable nor cacheable

0 1

prefetchable but not cacheable

1 0

both prefetchable and cacheable

1 1

reserved, do not use this combination

bit 13-15

base address register for CardBus
