A bus is merely a set of wires and a rigidly defined protocol that specifies a set of messages that can be sent on the wires. The messages are conveyed by patterns of electrical voltages applied to the wires with defined timings.

WebInterrupt system (x86) Hardware Interrupts - Priority Allocation by Daisy-Chaining [2] • The INTA signal passes from one peripheral to the next only if the peripheral is not requesting an interrupt. • The first peripheral in the daisy-chain has the highest priority and the last peripheral has the lowest priority (fixed scheme)

WebInterrupt ack would be interrupt from this device, and M1, and IOR and no interrupt from other device. There's no need to latch the interrupt signals as the device itself will latch the interrupt status until it's been serviced.
