The Clock Monitor detects if the user clock frequency exceeds or goes below the required frequency.
Note: The Clock Underrun signal might also go High during the stop condition, if the frequency of the signals goes much lower than the desired frequency.
Note: There might be cases where OOR/glitch is not detected if there is a large difference between the maximum user clock frequency (e.g., 280 MHz) and minimum user clock frequency (e.g., 10 MHz).
