The Clock Monitor detects if the user clock frequency exceeds or goes down below the required frequency.
Note: Clock under run signal can also
go high during the stop condition, if the frequency of the signals goes much lower than
the preferred frequency.
Note: There might be cases where
OOR/Glitch is not detected if the difference between maximum user clock frequency (for
example, 280 MHz) to minimum user clock frequency (for example, 10 MHz) is huge.
