Please let me know the Oscillator Input Calibration Adjustment(OSCin_FREQ[7:0] --, R13,bit14-21) function in detail ? If uset doesn't set a right frequency to the resister, does the device work well ?

    The calibration OSCin_FREQ input frequency select is simply set to the OSCin frequency used in design to ensure the calibration routine runs reliably.

    Timothy, thank you very much for your help. But. I want to know the following ; My customer didnot change the resister value from default, And he is using 33MHz reference frequency, there is no error and no toruble on the PLL. So he asked me that does it must set the resister to a right value ? I cannot find the meaning of the resister, please let me know a internal mechanism of the "Oscillator Input Calibration Adjustment" ?
