In OCD Calibration mode, DDR Controller must compare the voltage of DQ,DQS/DQSN which DDR2 SDRAM output.
I don't know how can I compare the DQ,DQS/DQSN voltage is all right??
Are we just need to compare the high level('1') or low level('0') of the DQ,DQS/DQSN pin?
Is anybody know how to do OCD Calibration of DDR2,especially the adjust mode of OCD. Thank you very much.
