Guaranteed Input and Output Parameters (Pin-to-Pin)
All values listed below are tested directly, and guaranteed over the operating conditions. The same parameters can also be derived
indirectly from the IOB and Global Buffer specifications. The XACT delay calculator uses this indirect method. When there is a
discrepancy between these two methods, the values listed below should be used, and the derived values must be ignored.

Timing is measured at pin threshold, with 50 pF external capacitive loads (incl. test fixture). When testing fast outputs, only one
output switches. When testing slew-rate limited outputs, half the number of outputs on one side of the device are switching. These
parameter values are tested and guaranteed for worst-case conditions of supply voltage and temperature, and also with the most
unfavorable clock polarity choice.
