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 follow-
ing timing diagram.
