Detailed explanation-1: -Maskable interrupts are those that may be accepted or ignored by the CPU based on their priority. In contrast, the CPU must accept the non-maskable interrupts. A hardware interrupt that could be ignored by setting a bit in the interrupt mask register’s (IMR) bit-mask is referred to as a maskable interrupt.
Detailed explanation-2: -(ˈmɑːskəbəl ) adjective. capable of being masked.
Detailed explanation-3: -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.
Detailed explanation-4: -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.
