B/D/F/Type: 0/0/0/PCI 

Address Offset: 

8h 

Default Value: 

02h 

Access:  

RO; 

Size: 8 

bits 

This register contains the revision number of the CPU Uncore Device #0. These bits 
are read only and writes to this register have no effect. 

7:0 RO  02h  Core 

Revision Identification Number (RID):  
This is an 8-bit value that indicates the revision 
identification number for the CPU Uncore Device 
0. For the A-0 Stepping, this value is 00h.  
00h: A-0 
01h: A-1 
02h: B-0 

B/D/F/Type: 0/0/0/PCI 

Address Offset: 

9-Bh 

Default Value: 

060000h 

Access:  

RO; 

Size: 24 

bits 

This register identifies the basic function of the device, a more specific sub-class, and 
a register-specific programming interface. 

23:16 RO 

06h  Core 

Base Class Code (BCC):  
 This is an 8-bit value that indicates the base 
class code for the CPU Uncore. This code has 
the value 06h, indicating a Bridge device. 

15:8 RO  00h  Core 

Sub-Class Code (SUBCC):  
 This is an 8-bit value that indicates the 
category of Bridge into which the CPU Uncore 
falls. The code is 00h indicating a Host Bridge. 

7:0 RO  00h  Core 

Programming Interface (PI):  
 This is an 8-bit value that indicates the 
programming interface of this device. This value 
does not specify a particular register set layout 
and provides no practical use for this device.
