Note 1 All parameters are individually tested and guaranteed Interpreting this data by numerically adding two or more parameters to create a new timing
specification may lead to invalid results
Note 2 The maximum value for this parameter is the latest WAIT can be removed without adding an additional T-state The formula assumes a minimum external
wait of one T-state
