2.1.5. Interrupt Enable Flag

Try these first

1. 1.

   What does the Interrupt Enable Flag control?

   Hint

   Think of what happens when the flag is set to 1.

2. 2.

   What occurs when the Interrupt Enable Flag is set to 0?

   Hint

   Consider how this impacts program execution.

3. 3.

   What does the Interrupt Enable Flag control?

   • A) Memory allocation
   • B) CPU processing speed
   • C) Allowing or disabling interrupts

   Hint

   Think about what the flag actually does during execution.

4. 4.

   When the Interrupt Enable Flag is set to 0, what happens?

   • True
   • False

   Hint

   Consider the implications on program operations.

5. 5.

   Consider a digital system where numerous interrupts are generated rapidly. Discuss the implications if the Interrupt Enable Flag is mistakenly left disabled, and propose how to rectify this mistake without causing system errors.

   Hint

   Focus on both the immediate repercussions and long-term corrective actions.

6. 6.

   Create a flowchart that showcases how the state of the Interrupt Enable Flag influences the operations of other flags during program execution.

   Hint

   Use clear symbols to mark decisions and results for better clarity.
