Asynchronous GTL+ Signals
Legacy input signals (such as A20M#, IGNNE#, INIT#, SMI#, SLP#, and STPCLK#) use CMOS
input buffers. All of these signals follow the same DC requirements as GTL+ signals; however, the
outputs are not actively driven high (during a logical 0-to-1 transition) by the processor. These
signals do not have setup or hold time specifications in relation to BCLK[1:0].

2.7
Test Access Port (TAP) Connection
Due to the voltage levels supported by other components in the Test Access Port (TAP) logic, it is
recommended that the processor be first in the TAP chain and followed by any other components
within the system. A translation buffer should be used to connect to the rest of the chain unless one
of the other components is capable of accepting an input of the appropriate voltage level. Similar
considerations must be made for TCK, TMS, TRST#, TDI, and TDO. Two copies of each signal
may be required, with each driving a different voltage level.
