Parameter Interpretation
The parameters listed in the following partly represent the characteristics of the C161K/
O 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 C161K/O will provide signals with the respective timing characteristics.
SR (System Requirement):
The external system must provide signals with the respective timing characteristics to
the C161K/O.
