NOTES:
1.
1.
Refer to
for signal descriptions and
termination requirements.
2.
In processor systems without a debug port implemented on the board, these signals are used to support
debug port interposers. In systems with the debug port implemented on the board, these signals are no
connects.
debug port interposers. In systems with the debug port implemented on the board, these signals are no
connects.
3.
BPM[2:1]# and PRDY# are AGTL+ output only signals.
4.
PROCHOT# signal type is open drain output and CMOS input.
5.
On-die termination differs from other AGTL+ signals, please contact your Intel representative for more
details.
6.
When paired with a chipset limited to 32-bit addressing, A[35:32] should remain unconnected.
