Reserved or Unused Signals

All Reserved (RSVD) signals must remain unconnected. Connection of these signals to
V , V
CC TTA
result in component malfunction or incompatibility with future processors. See
Chapter 4
For reliable operation, always connect unused inputs or bi-directional signals to an
appropriate signal level, except for unused integrated memory controller inputs,
outputs, and bi-directional pins which may be left floating. Unused active high inputs
should be connected through a resistor to ground (V
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.
