Abstract
A controller circuit can provide communication paths between multiple host devices and at least one function interface (I/F), where a function I/F can allow access to a predetermined circuit function. The controller circuit can include an endpoint buffer circuit having a plurality of storage locations configurable as endpoints according to a predetermined data transmission protocol and a data switching circuit coupled to the endpoint point buffer circuit. The data switching circuit is configurable to provide communication paths that enable a first host I/F and a second host I/F to access at least a same function I/F, and enable the first and second host I/Fs to communicate with one another.
