The count can be reset to 0 at any time. Again there is both a reset message that
can be sent from the PC and an
optional hardware reset signal.
Whether the hardware “reset” and “enable” are used is determined by how the

Input Signal
The input pulse train is a repetitive square wave input that look s something like
the following:
If you know the maximum frequency of the pulse train, you can configure the
pulse counter to count pulse up to that pulse rate. In doing so, the counter will
consider anything above the maximum rate that you have defined
to be noise
and will ignore it.
