Datasheet
Modem CIS address space: 100H to 1FFH (loaded from EEPROM)
9.3.2
Modem Base I/O Addressing
The modem base I/O addressing is an 8-byte address space. During I/O cycles, accesses to the
modem port are byte accesses. FLA3 is kept low while FLA[2:0] are mapped according to the PCI
byte address offset.
9.3.3
Modem CardBus CSTCHG Registers
The modem CardBus CSTCHG registers are used in CardBus mode only. There are four event
related registers. The CardBus software uses the registers to determine which event has occurred
and manage the event and to control the CSTSCHG signal. The 82559 supports only the interrupt
and general wake-up event bits in the CSTSCHG registers. These registers compliment the PCI
Power Management registers for the use with non-ACPI compliant OS. It is initialized by power-up
reset driven on the ALTRST# pin.
9.3.3.1
Modem Function Event Register
The Modem Function Event register specifies the event that changed its status. It is identical to the
Ethernet Function Event register described in
Section 9.1.14.1, “LAN Function Event Register” on
page 77
