Power Management Signals
Table 7 provides descriptions of the power management signals. The SM_CLK and SM_DATA
signals refer to the two-wire serial SMBus interface. Although this interface is currently used
solely for the digital thermal sensor, the SMBus contains reserved serial addresses for future use.
NOTE: V_3ALWAYS is a 3.3-V supply and is generated whenever V_DC is available and supplied to the
PIIX4E/M resume well.

Power Management Signal Descriptions
Name
Type
Voltage
Description
SUS_STAT1#
I
CMOS
V_3ALWAYS
Suspend Status: This signal connects to the SUS_STAT1#
output of the PIIX4E/M. SUS_STAT1# provides information on
the host clock status and is asserted during all suspend states.
VR_ON
I
CMOS
V_3
VR_ON: Voltage regulator ON. This 3.3-V (5.0-V tolerant) signal
controls the operation of the voltage regulator. VR_ON should
be generated as a function of the PIIX4E/M SUSB# signal,
which is used for controlling the “Suspend State B” voltage
planes. This signal should be driven by a digital signal with a
rise/fall time of less than or equal to 1
S. (V
IL,max =0.4V, VIH,min
=3.0V.)
VR_PWRGD
O
V_3
VR_PWRGD: This signal is driven high by the mobile module to
indicate that the voltage regulator is stable and is pulled low
using a 100-K resistor when inactive. It can be used in some
combinations to generate the system PWRGOOD signal.
BXPWROK
I
CMOS
V_3
Power OK to BX: This signal must go active at least 1 mS after
the V_3 power rail is stable and 1 mS prior to deassertion of
PCIRST#.
SM_CLK
I/O D
CMOS
V_3
Serial Clock: This clock signal is used on the SMBus interface
to the digital thermal sensor.
SM_DATA
I/O D
CMOS
V_3
Serial Data: An open-drain data signal on the SMBus interface
to the digital thermal sensor.
ATF_INT#
O D
CMOS
V_3
ATF Interrupt: An open-drain output signal of the digital thermal
sensor.
