11.6 CLKinX Control Page

The

CLKinX Control

page allows to the user to enter the input frequency at the different CLKinX pins, change the

mode by which the active CLKinX is selected, and change the routing options for the CLKinX inputs.

You can also reset the PLL1 R or PLL2 N divider on this page.
