The digital blocks feature the same glitch filter function that is
available on the SFDs. This enables the user to ignore spurious
transitions on the inputs. For example, the filter can be used to
debounce a manual reset switch.
When configured as digital inputs, each VXn pin has a weak
(10 μA) pull-down current source available for placing the input
in a known condition, even if left floating. The current source, if
selected, weakly pulls the input to GND.
