Abstract
A controller circuit provides communication paths between multiple host devices and a target device. The controller circuit includes a first host idle detection circuit that determines when a first host interface (I/F) is in an idle state, an idle state being when the first host I/F is not communicating with the controller circuit. A switch circuit can selectively enables a controllable communication path between a second host I/F and a target device I/F. A first response circuit can be coupled to the first host I/F and output predetermined responses from the first host I/F in response to communications received on the first host I/F. The first response circuit outputting a predetermined response when at least the controller circuit has enabled the controllable communication path between a second host I/F and the target device I/F and disabled the controllable communication path between the first host I/F and the target device I/F.
