82801DB ICH4 Datasheet
Note: The data register is an 8-bit read only register that provides a mechanism for the ICH4’s integrated
PCIDATA — PCI Power Management Data Register
(LAN Controller—B1:D8:F0)
Offset Address:
Default Value:
LAN controller 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 W to 2.55 W
with 0.01 W resolution, scaled according to the Data Scale field in the PMCSR. The structure of
the Data Register is given in

State dependent power consumption and heat dissipation data.
Power State — R/W. This 2-bit field is used to determine the current power state of the integrated
LAN controller, and to put it into a new power state. The definition of the field values is as follows:
00 = D0
01 = D1
10 = D2
11 = D3
