4.2.9. Clock Switchover

The clock switchover feature allows the PLL to switch between two reference input clocks. Use this feature for clock redundancy or for a dual-clock domain application, such as a system that turns on the redundant clock if the previous clock stops running. Your design can automatically perform clock switchover when the clock is no longer toggling, or based on the user control signal, clkswitch.
