Single Pulse Generation

The counter can output a single pulse. The pulse appears on the Counter n
Internal Output signal of the counter.
You can specify a delay from when the counter is armed to the beginning
of the pulse. The delay is measured in terms of a number of active edges of
the Source input.
You can specify a pulse width. The pulse width is also measured in terms
of a number of active edges of the Source input. You also can specify the
active edge of the Source input (rising or falling).
