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).
Figure 7-22 shows a generation of a pulse with a pulse delay of four and a pulse width of three
(using the rising edge of Source).
