CLK
1. These parameters account for the number of clock cycles and depend on the operating frequency of the clock as follows: the num-
ber of clock cycles = specified value of timing/clock period (count fractions as a whole number).
2. The set up and hold times refer to the addition of the register. Note that although the Buffered set up times appear much greater,
there is no additional clock cycle as there is in Registered Mode.
