Figure 21. Modem PCI Configuration Registers
Data Register
The data register is an 8-bit read only register that provides a mechanism for the 82551QM to
report state dependent maximum power consumption and heat dissipation. The value reported in
this register depends on the value written to the Data Select field in the PMCSR register. The power
measurements defined in this register have a dynamic range of 0 to 2.55 W with 0.01 W resolution
according to the Data Scale. The value in this register is hard-coded in the silicon. The structure of
the data register is listed in
Function 1: Modem PCI Configuration Space
In PCI and CardBus system, the 82551QM 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.
