Raghunathan said:
Case 2 : Level Trigger A latched Emergency switch signal that goes low and remains low till the user releases it. As long as it is not released, the ISR loop is valid. But Raghu, if I am not wrong, there is one catch to that... If the Level of the Signal on the pin remains to be low even after the interrupt is serviced, the interrupt re-occurs. In-short, you should see that the level goes to high within the time the ISR executes or else the interrupt re-occurs... -Harsha. |
