#102826 - if it is level, it need to remain Responding to: ???'s previous message |
Some logic is missing in this "correct" answer! If level - but it is level. Will be one or the other ? Yes ! No ! not that I see When I set IE.7 again will the interrupt be handled or ignored? YES, if level activated, the interruput will be lost if the level does not remain NO if edge triggered, the interupt will happen at enabling. but since you seem not to understand here we go The "interrupt flag" is latched on edge triggered interrupts (ITn = 1) and will remain till the interrupt is enabled. For level interrupts (ITn = 0) the level need remain till the interrupt is enabled. Why can you not use edge triggered (when goes low set flag) as opposed to level acti=veted (when low flag is low)?
