Gigabit LAN Configuration Registers  
12.1.22 DR—Data Register  
(Gigabit LAN—D25:F0)  
Address Offset: CFh  
Attribute:  
Size:  
RO  
8 bits  
Default Value:  
See bit description  
Bit  
Description  
Reported Data (RD) — RO. This register is used to report power consumption and  
heat dissipation. This register is controlled by the Data_Select field in the PMCS (Offset  
CCh, bits 12:9), and the power scale is reported in the Data_Scale field in the PMCS  
(Offset CCh, bits 14:13). The data of this field is loaded from the NVM if PM is enabled  
in the NVM or with a default value of 00h otherwise.  
7:0  
12.1.23 CLIST 2—Capabilities List Register 2  
(Gigabit LAN—D25:F0)  
Address Offset:  
Default Value:  
D0h–D1h  
E005h  
Attribute:  
Size:  
R/WO, RO  
16 bits  
Function Level Reset: No (Bits 15:8 only)  
Bit  
Description  
Next Capability (NEXT) — R/WO. Value of E0h points to the Function Level Reset  
capability structure.  
15:8  
These bits are not reset by Function Level Reset.  
Capability ID (CID) — RO. Indicates the linked list item is a Message Signaled  
Interrupt Register.

64-bit Capable (CID) — RO. Set to ‘1’ to indicate that the GbE LAN Controller is  
capable of generating 64-bit message addresses.  
Multiple Message Enable (MME) — RO. Returns 000b to indicate that the GbE LAN  
controller only supports a single message.  
6:4  
3:1  
Multiple Message Capable (MMC) — RO. The GbE LAN controller does not support  
multiple messages.  
MSI Enable (MSIE) — R/W.  
0 = MSI generation is disabled.  
1 = The Gb LAN controller will generate MSI for interrupt assertion instead of INTx  
signaling.
