Processor I/O Ring:
Powers processor interface signals such as the
PIIX4E open-drain pullups for the processor/PIIX4E sideband signals
and the CKDM66-M clock source.
3.1.8
JTAG (7 Signals)
Table 8 lists the ITP/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, since the definition of the ITP interface has
changed between the Pentium
processor and mobile
Pentium II processor generations.

Debug Port Signals:
Currently defined for the generation of
Pentium
processors. These signals are not used in the Pentium
II processor mobile module, and should not be connected.
NOTE:
DBREST# (reset target system) on the ITP debug port can be “l(fā)ogically ANDed” with VR_PWRGD TO PIIX4E’s PWROK.
