DC Input:
5V-21V.
V_3S

SUSB# controlled 3.3V:
V_3S is supplied by the system electronics. This is a 3.3V power
supply that is turned off during suspend during system states STR, STD, and Soff.
V_5
I
1
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.
V_3
I
5
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.
V_CPUIO
O
3
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.
3.1.8
JTAG (7 Signals)
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 cannot be used as an ITP port,
since the definition of the ITP interface has changed
between the generations of the mobile Pentium processor
and the mobile Pentium II processor with on-die cache.
