Power Sequencing Signals
Signal Name
Description
Direction / Buffer
Type
PROCPWRGD
The processor requires this input signal to be a clean
indication that the V
CC
 and V
DDQ
 power supplies are
stable and within specifications. This requirement
applies regardless of the S-state of the processor.
'Clean' implies that the signal will remain low (capable
of sinking leakage current), without glitches, from the
time that the power supplies are turned on until the
supplies come within specification. The signal must
then transition monotonically to a high state.
I
Asynchronous CMOS
VCCST_PWRGD
The processor requires this input signal to be a clean
indication that the V
CCST
 and V
DDQ
 power supplies are
stable and within specifications. This single must have
a valid level during both S0 and S3 power states.

Asynchronous CMOS
PROC_DETECT#
Processor Detect: This signal is pulled down directly
(0 Ohms) on the processor package to ground. There
is no connection to the processor silicon for this signal.
System board designers may use this signal to
determine if the processor is present.

VCC
Processor main power rail.
Ref
VDDQ
Processor I/O supply voltage for DDR3L/DDR3L-RS/
LPDDR3.

VCCST
Sustain voltage for the processor in standby modes
Ref
VIDSOUT
VIDSCLK
VIDALERT#
VIDALERT#, VIDSCLK, and VIDSCLK comprise a three
signal serial synchronous interface used to transfer
power management information between the
processor and the voltage regulator controllers.
I/O CMOS
O CMOS
I CMOS
VR_EN
Sideband output from the processor which controls
disabling of the VR when the processor is in the C10
state. This signal will be used to disable the VR only if
the processor is configured to support VR disabling
using VR_CURRENT_CONFIG MSR (601h).
O
VR Enable CMOS
VR_READY
Sideband signal which indicates to the processor that
the external voltage regulator for the V
CC
 power rail is
valid.
