Abstract:
Aspects of the present disclosure are directed to facilitating communications to respective circuit nodes in a manner that may also be useful for mitigating undesirable signal attenuation. As may be implemented in accordance with one or more embodiments, switchable isolation circuits, presented by at least one transformer and switch, are utilized to isolate adjacent data processing nodes on a bus in which each data processing node includes logic circuitry and processes signal therein. For each of the switchable isolation circuits, switching circuitry operates to mitigate communication propagation over the differential bus between adjacent data processing nodes, by switching the switchable isolation circuit for providing isolation. This approach may be utilized, for example, to assign sequential identification to daisy-chained circuit nodes upon start-up or reset, for use in addressing each node directly for further communication therewith.

Claim (Index 14):
An apparatus comprising:\n a communication bus having at least two bus lines; a switchable isolation circuit configured and arranged to mitigate signal propagation between circuit nodes on the communication bus, the switchable isolation circuit including, for each bus line, switching circuitry and a switched isolation transformer having a first winding configured and arranged for connection in series between the circuit nodes on the bus line, and a second winding connected to the switching circuitry and configured and arranged with the switching circuitry to effect isolation of the bus line connected in series with the first winding; in a first one of the circuit nodes, communication-logic circuitry configured and arranged for connection to the bus lines for communicating data thereon, and including a logic circuit configured and arranged to, in response to a communication event involving the first one of the circuit nodes, switch the switching circuitry connected to the second winding off and therein mitigate passage of signals through the first winding of each switched isolation transformer; a master circuit node connected to communicate on the communication bus; and a plurality of the circuit nodes including the first one of the circuit nodes, wherein the master circuit node is configured and arranged with the switchable isolation circuit to assign an identification to each sequential one of the circuit nodes by\n utilizing the switchable isolation circuit for one of the circuit nodes to mitigate propagation of signals beyond the one of the circuit nodes while the master circuit node assigns an identification thereto, and \n after the one of the circuit nodes has been assigned an identification, ceasing mitigating the propagation of signals.
