Signal Name
Description
Direction
Type
GFX_DPRSLPVR
GPU output signal to a VRD11.1 compliant VR. When
asserted this signal indicates that the GPU is in render
suspend mode. This signal is also used to control render
suspend state exit slew rate.
Note: This signal is not used by the processor. It is

connected to V
SS
on the package.
GFX_VID[6:0]
GFX_VID[6:0] (Voltage ID) pins are used to support
automatic selection of nominal voltages (VAXG). These
are CMOS signals that are driven by the processor. The
VID code output by VID[6:0] and associated voltages are
.
Note: These signals are not used by the processor. They
are connected to V
TT
on the package.
GFX_VR_EN
GPU output signal to GPU VR. This signal is used as an
on/off control to enable/disable the GPU VR.
Note: This signal is not used by the processor. It is

are no connect on the package.
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.
Note: This signal is not used by the processor. It is a no
