GFX_DPRSLPVR

Integrated graphics output signal to a VRD11.1 compliant 

VR. When asserted this signal indicates that the 

integrated graphics is in render suspend mode. This 

signal is also used to control render suspend state exit 

slew rate. 

O

CMOS

GFX_IMON

Current Sense from an VRD11.1 compliant VR to the 

integrated graphics. 
Note: This signal is not used by the processor at this 

time, it is reserved for possible future use. 

I

Analog

GFX_VID[6:0]

GFX_VID[6:0] (Voltage ID) pins are used to support 

automatic selection of nominal voltages (V

AXG

). These are 

CMOS signals that are driven by the processor. The VID 

code output by VID[6:0] and associated voltages are 

given in 

. 

O

CMOS

GFX_VR_EN

Integrated graphics output signal to integrated graphics 

VR. This signal is used as an on/off control to 

enable/disable the integrated graphics VR.

CMOS

VAXG

Graphics core power supply. 

PWR

VAXG_SENSE

VAXG_SENSE and VSSAXG_SENSE provide an isolated, 

low impedance connection to the VAXG voltage and 

ground. They can be used to sense or measure voltage 

near the silicon.

Analog

VCCPLL

VCCPLL provides isolated power for internal processor 

PLLs.

PWR

VDDQ

Processor I/O supply voltage for DDR3.

PWR

VSSAXG_SENSE

VAXG_SENSE and VSSAXG_SENSE provide an isolated, 

low impedance connection to the VAXG voltage and 

ground. They can be used to sense or measure voltage 

near the silicon. 

Analog

VSS

VSS are the ground pins for the processor and should be 

connected to the system ground plane.

GND

CGC_TP_NCTF

Corner Ground Connection: This land may be used to test 

for connection to ground. A test point may be placed on 

the board for this land. This land is considered Non-

Critical to Function.
