 outlines the signals which include on-die termination (R

TT

) and lists signals which include 

additional on-die resistance (R

L

). O.pen drain signals are also included. 

 provides signal 

reference voltages

1. Signals that do not have R

TT

, nor are actively driven to their high voltage level.

2. The termination for these signals is not R

TT

. The OPTIMIZED/COMPAT# and BOOT_SELECT pins have a 

500 - 5000

 Ω pull-up to V

TT

.

1. These signals also have hysteresis added to the reference voltage. See 

 for more information.

The Intel® Xeon™ processor with 800 MHz system bus does not use CMOS voltage levels on any 
signals that connect to the processor silicon. As a result, input signals such as A20M#, 
FORCEPR#, IGNNE#, INIT#, LINT0/INTR, LINT1/NMI, SMI#, SLP#, and STPCLK# use GTL
