Case #2: Input Clock Failure: Switching from a
selected clock stuck HIGH to a valid clock (RPE
enabled).
If CLK1 fails HIGH before the RPE MUX selects
CLK2 (using the SEL pin), the switchover will occur
in three stages.
Note: Output shows extended clock cycle during switchover. Pulse width for both high and low of this cycle will always be
greater than 50% of the CLK2 period.
