     Recently, we have changed imx53's DDR from DDR3-1333 to DDR3-1666. I had some questions about the ESDCTL setting in  imx53RM.pdf.

    for example:

               the ESDCTL_ESDOTC register, bit[29-27]:tAOFPD, the unit is cycle ; but bit[23-20] tANPD, the unit is clock .

               I don't konw what is the different between    cycle   and    clock .


  who can help me !

     thanks !
