Parameter Interpretation

The parameters listed in the following partly represent the characteristics of the C167CR
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 C167CR will provide signals with the respective timing characteristics.
SR (System Requirement):
The external system must provide signals with the respective timing characteristics to
the C167CR.
