Figure 12: Example of One-Shot Mode Using a 50% Duty Cycle
Repetitive One-Shot
Use repetitive one-shot mode to generate a pulse output signal each
time the module detects a trigger (determined by the gate input
signal). You can use this mode to clean up a poor clock input signal
by changing its pulse width, then outputting it.
In repetitive one-shot mode, the internal C/T clock source is more
useful than an external C/T clock source; refer to
page 47 for more
information on the internal C/T clock source.
