60.6.3.3.9.4 External Filtering in Dynamic Mode

A majority vote filter is used to adapt filter cut-off sensitivity (preventing a false detection due to any spurious pulses).

The filter can be configured through SECUMOD_PIOBUx.FILTER3_5. All pulses less than t_ICLK/8 or t_ICLK/4 are filtered when FILTER3_5 is low (default) or high, respectively.
