The following table indicates the mapping of all I/O re-
sources that are accessible through the Am79C930
PCMCIA system interface. Note that some resources
are physically located within the BIU, while others are lo-
cated in the TAI and still others exist as external Flash
and SRAM:

ISA Plug and Play Mode Resources
The Am79C930 device fully supports the ISA Plug
and Play specification, revision 1.0a, including the
Plug and Play ADDRESS Auto-configuration port,
WRITE_DATA Auto-configuration port, READ_DATA
Auto-configuration port, and 19 of the Plug and Play
configuration registers, as well as providing a mecha-
nism for access to Flash memory for reading the
Am79C930 device’s Plug and Play Resource Data.
The following table indicates the range of I/O and mem-
ory addresses to which the Am79C930 device will re-
spond when operating in the ISA Plug and Play mode.
