Programing Interface—82583V GbE Controller
10.1.3.6
Data Register, Offset 0xCF, (RO)
This optional register is used to report power consumption and heat dissipation.
Reported register is controlled by the Data_Select field in the PMCSR and the power
scale is reported in the Data_Scale field in the PMCSR. The data of this field is loaded
from the NVM if power management is enabled in the NVM. Otherwise, it has a default
value of 0x00. The values for the 82583V are as follows:
10.1.4
Note:

Data Select
Function 0
D0 (Consume/Dissipate)
(0x0/0x4)
EEPROM address 0x22
D3 (Consume/Dissipate)
(0x3/0x7)
EEPROM address 0x22
For other Data_Select values the Data register output is reserved (0b).
Message Signaled Interrupt (MSI) Configuration Registers
This structure is required for PCIe devices. Initialization values of the configuration
registers are marked in parenthesis. Light-blue fields represent read-only fields.
There are no changes to this structure from the PCI 2.2 specification.
