Question:
Which of the following has the highest priority?
Which of the following has the highest priority?
Show Hint
NMI stands for
\[
\boxed{\text{Non-Maskable Interrupt}}
\]
It cannot be disabled and is generally used for emergency conditions.

- NMI
- RESET
- External interrupt
- Software interrupt
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Recall interrupt priorities.
Among processor interrupts, the Non-Maskable Interrupt (NMI) has the highest interrupt priority because it cannot be disabled by software.
Step 2: Choose the correct option. Since NMI is serviced before other interrupts, \[ \boxed{\text{NMI}} \] has the highest priority. Therefore, \[ \boxed{(A)} \] is the correct answer.
Step 2: Choose the correct option. Since NMI is serviced before other interrupts, \[ \boxed{\text{NMI}} \] has the highest priority. Therefore, \[ \boxed{(A)} \] is the correct answer.
