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.
