3.1.7
Table 7 lists the voltage signal definitions.
3.1.8
Table 8 lists the JTAG signals, which the system electronics
can use to implement a JTAG chain and ITP port, if desired.
The JTAG signals provided can not be used as an ITP port.
DBREST# (reset target system) on the ITP debug port can be “logically ANDed” with VR_PWRGD TO PIIX4E/M’s PWROK.

Voltage
DC Input: 5V-21V.
SUSB# controlled 3.3V: V_3S is supplied by the system electronics. This is a 3.3-V power
supply that is turned off during suspend during system states STR, STD, and Soff.
SUSC# controlled 5V: Power managed 5.0-V supply. An output of the voltage regulator on
the system electronics. This rail is off during STD and Soff.
SUSC# controlled 3.3V: Power managed 3.3-V supply. An output of the voltage regulator on
the system electronics. This rail is off during STD and Soff.
Processor I/O Ring: Powers the processor interface signals such as the PIIX4E/M open-drain
pullups for the processor/PIIX4E/M sideband signals and the CKDM66-M clock source.
JTAG Test Data Out: Serial output port. TAP instructions and data is shifted out of the
processor from this port.
JTAG Test Data In: Serial input port. TAP instructions and data is shifted into the
processor from this port.
JTAG Test Mode Select: Controls the TAP controller change sequence.
JTAG Test Clock: Testability clock for clocking the JTAG boundary scan sequence.
JTAG Test Reset: Asynchronously resets the TAP controller in the processor.
Debug Port Signals: These signals are not used in the Celeron processor mobile
module MMC-1and should not be connected.
