Interrupt
A signal to the proccessor telling it that a device needs it's attention.When an interupt is called:-
- A mask is applied through use of the AND operator to see if the interrupt is important enough to take immediate control of the proccessor.
- If it is, the current values of all registers are almost always saved.
- Then the interrupt service routine is loaded and executed.
- Once this has finished, the proccessor may go back to whatever it was doing before, or it may invoke a ?scheduler to decide what to do next.
