POINT
• A coincidence detection interrupt occurs when the counter value
coincidence (X02) rises (from OFF to ON). This means that, if the
coincidence signal is reset and unless the counter value coincidence
(X02) is turned OFF, the next interrupt request will not be issued.
• Immediately after power-ON or reset of the programmable controller
CPU, the counter value coincidence (X02) turns ON, however, no
coincidence detection interrupt will occur.
For how to reset the counter value coincidence (X02), refer to Section 5.3
(Figure 5.8).
