ITP/JTAG (7 SIGNALS)
Table 8 lists the
Intel Mobile Module’s In-target
Probe (ITP)/JTAG signals, which the system
electronics 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.
Please check with your local Intel Sales
Representative
for
recommendations and requirements for a debug
port.

Debug Port Signals:
Currently defined for the generation of Pentium
processors. Future uses are not yet defined.
* - Termination for the ITP signals must be done on the system electronics. The Intel Mobile Module does not
provide series termination for these signals.
