This is in addition to the one in the main domain NAVSS subsystem that is used for general purpose communication. Describe the node for use with bootloaders and firmware that require this communication path which uses interrupts to corresponding micro controller interrupt controller. Mark the node as disabled since this instance does not have interrupts routed to the main processor by default for a complete description of the node.
