Global Configuration Parameters
Auxiliary Output Source Selection (AuxOutSrc[1:0])
Selects the source of the AUX_OUT signal.
Note:
Lock Output Configuration (AuxLockCfg)” on page
Auto R-Modifier Enable (AutoRMod)
Controls the automatic ratio modifier function.
Clock Skip Enable (ClkSkipEn)
This parameter enables clock skipping mode for the PLL and allows the PLL to maintain lock even when
the CLK_IN has missing pulses.
