WebIn edge-triggered mode, the interrupt is “noticed” only once, at step 1. 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. WebThe software assigns each interrupt to a handler in the interrupt table. An interrupt handler is just a routine containing a sequence of operations. Each of these may request input and output while running. The routine for handling a specific interrupt is known as the interrupt service routine for the specific interrupt.
