Off-Chip Driver (OCD) Impedance Adjustment
DDR2 SDRAM supports driver calibration feature and the flow chart below is an example of the sequence.
Every calibration mode command should be followed by “OCD calibration mode exit” before any other com-
mand being issued. MRS should be set before entering OCD impedance adjustment and ODT (On Die Termi-
nation) should be carefully controlled depending on system environment.
