The 8086 microprocessor handles interrupts using a vectored interrupt mechanism. The interrupt handling process starts with an interrupt request signal sent to the processor by an external device. The processor then saves the current execution state of the program by pushing the flags, the code segment register (CS), and the instruction pointer (IP) onto the stack. It then retrieves the interrupt vector address from the interrupt vector table (IVT) using the interrupt number provided by the external device. The processor then jumps to the interrupt service routine (ISR) located at the address obtained from the IVT and executes the ______ _______ ________ _______ ______ ___ _________ __________ ______ _______ ______.
