NOTES:
1. Refer to
Section 5.2
for signal descriptions.
2. These AGTL+ signals do not have on-die termination. Refer to
Section 2.5
and the
ITP700 Debug Port
Design Guide
for termination requirements.
3. In processor systems where there is no debug port implemented on the system board, these signals are used
to support a debug port interposer. In systems with the debug port implemented on the system board, these
signals are no connects.
4. These signal groups are not terminated by the processor. Signals not driven by the ICH3-M component must
be terminated on the system board. Refer to
Section 2.5
, the
ITP700 Debug Port Design Guide,
and the
Mobile Intel
Pentium
4 Processor-M and Intel
845MP/845MZ Chipset Platform Design Guide
for termination
requirements and further details
.
5. The value of these pins during the active-to-inactive edge of RESET# defines the processor configuration
options. See
Section 7.1
for details.
