Function
Controls the noise removal for the TC1NF pin input.
If this is set to "0" (removal disabled), any input of more than 2/fsys
(25ns@fperiph=fc=80MHz) is accepted as a trigger input for TCCAP1, at whichever
level TC1IN pin is, "H" or "L."
If this is set to "1" (removal enabled), any input of less than 6/fsys
(75ns@fperiph=fc=80MHz) is regarded as noise and removed, at whichever level the
TC1IN pin is, "H" or "L." The range of removal changes depending on the selected
clock gear and a system clock used.
register (TCCAP1). If this is set to "00," the capture operation is disabled.
