MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -Answer. NMI stands for Non-masked Interrupt. All of the regular interrupts that we normally use and refer to by number are called maskable interrupts. The processor is able to mask, or temporarily ignore, any interrupt if it needs to, in order to finish something else that it is doing.

Detailed explanation-2: -In computing, a non-maskable interrupt (NMI) is a hardware interrupt that standard interrupt-masking techniques in the system cannot ignore.

Detailed explanation-3: -A non-maskable interrupt (NMI) is a type of hardware. interrupt (or signal to the processor) that prioritizes a certain thread. or process. Unlike other types of interrupts, the non-maskable interrupt cannot. be ignored through the use of interrupt masking techniques.

Detailed explanation-4: -NMI. It is a single non-maskable interrupt pin (NMI) having higher priority than the maskable interrupt request pin (INTR)and it is of type 2 interrupt.

Detailed explanation-5: -The 8086 has two hardware interrupt pins, i.e. NMI and INTR. NMI is a non-maskable interrupt and INTR is a maskable interrupt having lower priority. One more interrupt pin associated is INTA called interrupt acknowledge.
