These parameters depend on the cycle rate and these values are measured at a cycle rate with the minimum values of
t_CK, t_RC and I_RC.
These parameters depend on the output loading. The specified values are obtained with the output open.
Refer to output driver characteristics for the detail. Output Driver Strength is selected by Extended Mode Register.
