Input/Output Timing Chart
* Preset output goes ON when the count value exceeds the preset value of 100 and the preset output
goes OFF when its width reaches the set pulse width.
When the preset value exceeds 100, the preset value is changed to 200 (adding the preset count of
100 to the current preset value of 100).
Then, the preset output goes ON when the count value exceeds the preset value of 200, and the
preset output goes OFF when its width reaches the set pulse width.
When the preset value exceeds 200, the preset value is changed to 300 (adding the preset count of
100 to the current preset value of 200).
Note: When the one-shot pulse output function is selected, if its pulse width is large compared
with the update interval of the preset value, the output stays ON. To make sure to output
a one-shot pulse, set the preset value so that the conditions in the table below are
satisfied.
