Clock Switchover
Cyclone III Device Handbook, Volume 1

If you use the SignalTap
locked signal goes low only when areset is deasserted. If the areset signal is not
enabled, the extra logic is not implemented in the ALTPLL megafunction.

User
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.
Automatic Clock Switchover
Cyclone III device family PLLs support a fully configurable clock switchover
capability.
When the current reference clock is not present, the clock-sense block automatically
switches to the backup clock for PLL reference. The clock switchover circuit also
sends out three status signals—clkbad[0], clkbad[1], and activeclock—from
the PLL to implement a custom switchover circuit. You can select a clock source at the
backup clock by connecting it to the inclk1 port of the PLL in your design.
