Hi,
Regarding the advantage of the edge/level interrupt, it is dependent on the external triggering signal.
If you use level trigger, the disadvantage of level triggering is that if the external triggering source remains the valid level after the ISR is completed, the processor will reenter ISR.
If you use edge interrupt triggering, there is not above issue.
If the triggering signal is subject to noise, it seems that the level triggering is more immune to noise I suppose.
