 outlines the signals which include on-die termination (R

TT

). Open drain 

signals are also included. 

 provides signal reference voltages.

Signals that do not have R

TT

, nor are actively driven to their high voltage level.

2.

The on-die termination for these signals is not R

TT

. TCK, TDI, and TMS have an approximately 150 KΩ 

pullup to V

TT

.

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

 for more information.

 for signal FORCEPR# specifications.

Input signals such as A20M#, FORCEPR#, IGNNE#, INIT#, LINT0/INTR, LINT1/NMI, 
SMI# and STPCLK# utilize GTL+ input buffers.  Legacy output FERR#/PBE# and other 
non-AGTL+ signals IERR#, THERMTRIP# and PROCHOT# utilize GTL+ output buffers.  
All of these asynchronous GTL+ signals follow the same DC requirements as AGTL+ 
signals; however, the outputs are not driven high (during the electrical 0-to-1 
transition) by the processor. FERR#/PBE#, IERR#, and IGNNE# have now been defined 
as AGTL+ asynchronous signals as they include an active p-MOS device. Asynchronous 
GTL+ and asynchronous AGTL+ signals do not have setup or hold time specifications in 
relation to BCLK[1:0]; however, all of the asynchronous GTL+ and asynchronous 
AGTL+ signals are required to be asserted/deasserted for at least six BCLKs in order for 
the processor to recognize them.  See 

 for the DC specifications for the 

asynchronous GTL+ signal groups.

Due to the voltage levels supported by other components in the Test Access Port (TAP) 
logic, it is recommended that the processor(s) be first in the TAP chain and followed by 
any other components within the system. A translation buffer should be used to
