DIO#.FILTER
Description
Gets or sets the digital input filter when specified channel is configured as a digital input (see DIO#.DIR). The digital filter blocks input changes (rising or falling edges) until the minimum pulse width is exceeded. The +/- tolerance listed is the sample period (uncertainty) of the filter.
