4.2.1 Parameter Interpretation
The parameters listed in the following include both the characteristics of the XC2220U
and its demands on the system. To aid in correctly interpreting the parameters when
evaluating them for a design, they are marked accordingly in the column “Symbol”:
CC (Controller Characteristics):
The logic of the XC2220U provides signals with the specified characteristics.
SR (System Requirement):
The external system must provide signals with the specified characteristics to the
XC2220U.
