WebMar 4, 2024 · Maskable interrupt (IRQ): a hardware interrupt that may be ignored by setting a bit in an interrupt mask register’s (IMR) bit-mask. Non-maskable interrupt (NMI): a hardware interrupt that lacks an associated bit- mask, so that it can never be ignored. NMIs are used for the highest priority tasks such as timers, especially watchdog timers. WebMay 4, 2016 · With an interrupt, the chip has hardware to halt execution of the software, and jump to a special location for the interrupt handler. The interrupt handler often needs to save the state of the halted software, so that after the handler does its job, it can return to the software and pick up where it left off.
