| 1. A system within a node of a multiplexed communication system, wherein the node includes a controller for communication
over a multiplexed bus, the system comprising:
a transceiver coupled to a bus configured for receiving and transmitting messages over the bus;
a message buffer for storing one or more messages received by the transceiver;
a power interface that generates a power control signal suitable for coupling to a controller, wherein the controller enters
a power-on state in response to the power control signal; and
a controller interface suitable for coupling to a communication bus coupled to the controller providing communication between
the message buffer and the controller, wherein the controller interface is configured to transfer a message stored in the
message buffer to the controller;
wherein the controller interface is configured to send, in response to validating a received message for the controller, a
request via the controller interface that the controller wake-up.
