EOI Register
The EOI register is used to re-trigger the pulse interrupt signal to ensure that any nested interrupt events are serviced. The software interrupt handler must write to the EOI register at the end of the current interrupt processing routine, so that new events can re-trigger the pulse interrupt signal again. For level interrupt signals the EOI register is not functional and must not be used.
