Single Pulse Generation with Start Trigger
The counter can output a single pulse in response to one pulse on a
hardware Start Trigger signal. The pulse appears on the Counter n Internal
Output signal of the counter.
You can route the Start Trigger signal to the Gate input of the counter. You
can specify a delay from the Start Trigger to the beginning of the pulse. You
also can specify the pulse width. The delay and pulse width are measured
in terms of a number of active edges of the Source input.
After the Start Trigger signal pulses once, the counter ignores the Gate
input.
Figure 7-28 shows a generation of a pulse with a pulse delay of four and a
pulse width of three (using the rising edge of Source).
