Description
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.
Note: This signal is not used by the processor. It is
connected to V
on the package.
SS
Current Sense from an VRD11.1 compliant VR to the
integrated graphics.
Note: This signal is not used by the processor. It is
connected to V
on the package.
SS
GFX_VID[6:0] (Voltage ID) pins are used to support
automatic selection of nominal voltages (V
CMOS signals that are driven by the processor. The VID
code output by VID[6:0] and associated voltages are
given in
Chapter
7.
Note: These signals are not used by the processor. They
are connected to V
on the package.
TT
Integrated graphics output signal to integrated graphics
VR. This signal is used as an on/off control to
enable/disable the integrated graphics VR.
Note: This signal is not used by the processor. It is
connected to V
on the package.
SS
Graphics core power supply.
Note: These signals are not used by the processor. They
are no connect on the package.
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
connect on the package.
VCCPLL provides isolated power for internal processor
PLLs.
Processor I/O supply voltage for DDR3.
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
connected to V
on the package.
