Explain the following instructions of 8086

Instructions of 8086

NMI – Non maskable interrupt 

It cannot be stopped / masked by the software .

Used to handle the emergency situations . For eg : During power loss the program is saved using the NMI inst.

An external circuitry is there to detect power failure and to send an interrupt signal to 8086 through NMI line .

When AC fails , DC is supplied to allow computer to save program and when power comes came , the program can be restored from the point it was interrupted .

LOCK – makes instruction non-interruptable when processor is executing some instruction and is using common resources through system and it shouldnt be interrupted by another process .

till the LOCK is low ,  bus controller doesnt allow other process to take central  of system bus .
