Only when the interrupt line is cleared, and then reasserted, does the PIC consider another interrupt to have occurred. Neutrino allows ISR handlers to be stacked , meaning that multiple ISRs can be associated with one particular IRQ.

WebbA hardware interrupt is a condition related to the state of the hardware that may be signaled by an external hardware device, e.g., an interrupt request (IRQ) line on a PC, or detected by devices embedded in processor logic to communicate that the device needs attention from the operating system.
