Arrange the sequence of 8086 interrupts as per the priority assigned, from lowest to highest :
(1) Single step
(2) INTR
(3) NMI
(4) Divide error, Int n, INTO
Answer: B
From lowest to highest priority the order is (1) (2) (3) (4): single step, INTR, NMI, divide error/INT n/INTO.
In the 8086 the internal (software and exception) interrupts such as divide error, INT n and INTO have the highest priority, followed by the non-maskable interrupt NMI, then the maskable hardware interrupt INTR. The single-step (trap) interrupt has the lowest priority.
Option A makes single step the highest priority, the reverse of the truth, and options C and D place NMI below INTR, so none matches the 8086 priority list.
