PCI-to-CardBus Host Adapter
With this organization, bits 7:6 of the index value are used to select access to Socket A or Socket
B registers. In an ISA environment, bits 7:6 of the index value can also be used to select one of
four sockets when two PC Card host adapters are paired in a system.
Some older PC Card host adapters also allow setting of its older address pair to 03E2h and 03E3h
instead of the default 03E0h and 03E1h. This could allow up to eight sockets to be supported in a
system: four at the I/O address pair 03E0/03E1h and four at the I/O address pair 03E2/03E3h.
Bits 2:0 of this register can be used to map I/O space-accessible internal registers for a socket into
an I/O address pair and index range so that it appears as a particular socket number out of the
eight possible socket number locations found in older ISA-based PC Card host adapters.
Refer to Chapter 7 for information about the organization of the Index register.
