TopologyThree control lines are present in the External Control Bus for serving external interrupts: IRQ (Interrupt Request), IAK (Interrupt Acknowledge) and ISE (Interrupt Service End). These lines connect to all devices in Daisy Chain so any interrupter device can open the lines to avoid further propagation along the chain. This way, priority gets established by the "proximity" of the device to the CPU.
