Off-Chip Driver (OCD) Impedance Adjustment
DDR2 SDRAM supports driver calibration feature and the OCD Flow Chart is an example of sequence. Every
calibration 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 and ODT (On Die Termination) should be
carefully controlled depending on system environment.
