Table 5 lists the power management interface signals. The
SM_CLK and SM_DATA signals refer to the two-wire serial
SMBus interface. Although this interface is currently used
V_3ALWAYS is a 3.3-V supply. It is generated whenever V_DC is available and supplied to PIIX4E/M resume well.

OEM Pullup: This pullup resistor is not required on the Celeron processor mobile
module MMC-1.
Low-Power Mode For Cache SRAM: This signal is not used on the Celeron
processor mobile module MMC-1.
Suspend Status: This signal connects to the SUS_STAT1# outputs of PIIX4E/M. It
provides information on host clock status and is asserted during all suspend states.
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 us. (VIL(max)=0.4V, VIH(min)=3.0V.) See Figure 5, “Power-on-
Sequence Timing” for proper sequencing of VR_ON.
VR_PWRGD: This signal is driven high to indicate that the voltage regulator is
stable and is pulled low using a 100K resistor when inactive. It can be used in some
combination to generate the system PWRGOOD signal.
Serial Clock: This clock signal is used on the SMBus interface to the digital thermal
sensor. Ensure proper termination based upon the System Management Bus
Specification, Revision 1.0.
Serial Data: An open-drain data signal on the SMBus interface to the digital thermal
sensor. Ensure proper termination based upon the System Management Bus
Specification, Revision 1.0.
ATF Interrupt: This signal is an open-drain output signal of the digital thermal
solely for the digital thermal sensor, the SMBus contains
reserved serial addresses for future use. See Section 4.9 for
more details.
