Figure 27. Modem PCI Configuration Registers
Function 1: Modem PCI Configuration Space
In PCI systems and CardBus systems, the 82559 supports a dual function device: LAN/modem.
The LAN is defined as function zero, and the modem is defined as function one. The modem
function is active depending on the EEPROM setup.
The modem configuration registers define the resources required by the modem function. It is
meaningful in a multifunction card design only. Some of the modem configuration registers are a
reflection of their matched Ethernet registers. The registers’ values are pre-defined by hardware,
initialized by the EEPROM, or configurable through software. The shaded fields are described in
detail in the following subsections.
Modem Configuration ID Register
The Modem Configuration ID field is a Dword register composed of the Device ID and Vendor ID.
It is a read only register and its value is loaded from the EEPROM.
