The 8086 microprocessor uses interrupts to temporarily halt program execution, allowing peripheral devices to access the microprocessor. Interrupts trigger an interrupt service routine (ISR), a short program that instructs the microprocessor on how to handle the interrupt. There are two types of interrupts - software interrupts initiated by instructions, and hardware interrupts from external devices.

2. Interrupt
• Interrupt is the method of creating a
temporary halt during program execution and
allows peripheral devices to access the
microprocessor. The microprocessor responds
to that interrupt with an ISR (Interrupt Service
Routine), which is a short program to instruct
the microprocessor on how to handle the
interrupt.
