OFF CHIP DRIVER(OCD) IMPEDANCE ADJUSTMENT
DDR-II SDRAM supports driver calibration feature and the flow chart below is an example of sequence. Every calibra-
tion mode command should be followed by “OCD calibration mode exit” before any other command being issued. MRS
should be set before entering OCD impedance adjustment.
