Hi

Yes. You can use Input Glitch Filter for it.

The glitch width threshold can be adjusted easily by setting PORT_IOFLT0[FLTDIVn] between 1~4096 BUSCLKs (or 1~128 LPOCLKs).

The frequency of LPOCLK is 1KHz.

The BUSCLK depend on how you configure it.

Best Regards,

Robin

Hi Robin,

                Can you give me an example calculation for min and max range of filter time with BUSCLK 24 Mhz?
