Hardware interrupts coming from devices ignore this mechanism. 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. greenup lawn and shrub care
