Table 8 lists the
Intel Mobile Module’s In-target
Probe (ITP)/JTAG signals, which the I/O Module
can use to implement a processor debug port. The
system manufacturer can use debug port signals
on development-level boards, or on production
boards
for
manufacturing
testability.
Refer to the
Intel Mobile Module Design Guide
(Order Number 243339) for further details on
recommendations and requirements for a debug
port.
Termination for the ITP signals must be done on
the I/O Module. The Intel Mobile Module does not
provide series termination for these signals.

Debug Port Signals:
Currently defined for the generation of
Pentium processors. Future uses are not yet defined.
NOTE:
ITP(1:0) are used to define two pins for the debug port. At this time, these signals are defined as follows for
Pentium
processors:
