Parameter Interpretation
The parameters listed in the following partly represent the characteristics of the C164CI
and partly its demands on the system. To aid in interpreting the parameters right, when
evaluating them for a design, they are marked in column “Symbol”:
CC (Controller Characteristics):
The logic of the C164CI will provide signals with the respective characteristics.
SR (System Requirement):
The external system must provide signals with the respective characteristics to the
C164CI.
