#169998 - The datasheet tells you what is *guaranteed* to work
Responding to: ???'s previous message

2) In datasheet, it is mentioned that interrupt should be configured in level triggered mode

So do what the datasheet tells you - that is the only thing that is guaranteed to work!

but it is working in both the modes.

Outside of the datasheet specifications, the operation is undefined: this means that anything could happen - including that it appears to "work" under certain circumstances...
But you have no guarantee that this will be repeatable...
