For proper operation of adjust mode, WL = RL
1 = AL + CL
1 clocks and tDS/tDH should be met as the Output
Impedance Control Register Set Cycle. For input data pattern for adjustment, DT0 to DT3 is a fixed order and not
affected by MRS addressing mode (i.e. sequential or interleave).

Drive Mode
Drive mode, both drive (1) and drive (0), is used for controllers to measure DDR2 SDRAM Driver impedance before
OCD impedance adjustment. In this mode, all outputs are driven out tOIT after “Enter drive mode” command and all
output drivers are turned-off tOIT after “OCD calibration mode exit” command as the ”O(jiān)utput Impedance
Measurement/Verify Cycle”.
