The output driver impedance is selected by MR1[5,1] during initialization. The selected
value is able to maintain the tight tolerances specified if proper ZQ calibration is per-
formed. Output specifications refer to the default output driver unless specifically
stated otherwise. A functional representation of the output buffer is shown below. The
output driver impedance Ron is defined by the value of the external reference resistor
RZQ as follows:
