But at the runtime if i change the frequency from 1Khz to 2khz and then again i will set the duty for the same frequency like&nbsp;20 %,40% and 60% that time input capture unit capture the wrong duty cycle.</P><P>&nbsp;</P><P>Is their any limitation for input capture unit?</P><P>Regards,</P><P>Shrikant K</P><P>&nbsp;</P> Thu, 15 Jun 2023 12:27:18 GMT https://community.nxp.com/t5/S32K/Issue-in-capturing-Change-Frequency/m-p/1670288#M24021 shrikantkoli1995 2023-06-15T12:27:18Z https://community.nxp.com/t5/S32K/Issue-in-capturing-Change-Frequency/m-p/1670914#M24047 <P>Hi,</P> <P>there should not be limitation, but check if overflows could not happen on selected counter base.
