Reserved or Unused Signals
All Reserved (RSVD) signals must not be connected. Connection of these signals to V

CCPLL
, V
SS
, or to any other signal (including each other) can result in 
component malfunction or incompatibility with future processors. See 
 for a land listing of the processor and the location of all 
Reserved signals.
For reliable operation, always connect unused inputs or bi-directional signals to an 
appropriate signal level. Unused active high inputs should be connected through a 
resistor to ground (V
SS
). Unused outputs maybe left unconnected; however, this may 
interfere with some Test Access Port (TAP) functions, complicate debug probing, and 
prevent boundary scan testing. A resistor must be used when tying bi-directional 
signals to power or ground. When tying any signal to power or ground, a resistor will 
also allow for system testability. Resistor values should be within ± 20% of the 
impedance of the baseboard trace, unless otherwise noted in the appropriate platform 
design guidelines.

Signal Group Summary
Signals are grouped by buffer type and similar characteristics as listed in 
. The 
buffer type indicates which signaling technology and specifications apply to the signals.
