title: What happens when a interrupt occurs in RTOS while currently in any task or another ISR?
body: <p>I have read this <a href="https://stackoverflow.com/questions/33005248/what-is-the-correct-definition-of-interrupt-latency-in-rtos">question</a>, It is not a valid answer when one interrupt is executing it will not disable all the other interrupts always. It is based on the interrupt type (in some case we need to do manually in our program).</p>

    priority interrupt occurs the what will happen ?</p>
