| By checking the interrupt register after finishing the execution of the current instruction. | |
| By checking the interrupt register at fixed time intervals. |
Question 8 Explanation:
As soon as an interrupt is raised the corresponding register is set. But CPU acts on it only after execution of its current instruction. This is followed to ensure integrity of instructions.
