Which interrupt is a non-maskable interrupt?

Common examples of non-maskable interrupt include types of internal system chipset errors, memory corruption problems, parity errors and high-level errors needing immediate attention.

What is the interrupt type of NMI?

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. 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.
