Question

Explain Maskable Interrupts.

Answer 1

• Maskable interrupts are interrupts that can be enabled or disabled by the processor.
• They can be ignored (masked) when the processor is busy with higher priority tasks.
• These interrupts are controlled using interrupt enable/disable instructions.
• In the 8085 microprocessor, INTR is a maskable interrupt.
• Maskable interrupts are used for less critical operations.
• They allow better control over interrupt handling in a system.
