You can use Input Glitch Filter for it.</P><P>The glitch width threshold can be adjusted easily by setting PORT_IOFLT0[FLTDIVn] between 1~4096 BUSCLKs (or 1~128 LPOCLKs).</P><P>The frequency of LPOCLK is 1KHz.</P><P>The BUSCLK depend on how you configure it.</P><P><span class="lia-inline-image-display-wrapper" image-alt="Input glitch filter setting.png"><img src="https://community.nxp.com/t5/image/serverpage/image-id/14087iF7794D3E64736551/image-size/large?v=v2&amp;px=999" role="button" title="Input glitch filter setting.png" alt="Input glitch filter setting.png" /></span></P><P>Best Regards,</P><P>Robin</P><P style="min- padding: 0px;">&nbsp;</P><P>-----------------------------------------------------------------------------------------------------------------------<BR />Note: If this post answers your question, please click the Correct Answer button.
