May I ask interrupt handling sequence.


Could I use only variables flag when interrupt handling sequence.

Now I planning the following style of interrupt handling,
Is it possible ?, or Not.
 

It is challenging style of Interrupt handling.
Usually use event or signal for notify when interrupts happen.
But it exist little bit overhead that processing notification.
 

And  I try to cut out the time of notification.
Is it able to realize?
