What is the difference between maskable and non-maskable interrupts?
Answer
Maskable can be disabled; Non-maskable cannot.
Maskable interrupts can be delayed or rejected by the microprocessor (e.g., INTR in 8085). Non-maskable interrupts cannot be ignored and must be serviced immediately (e.g., TRAP in 8085).
