Nexus Aurora Router (NAR)
suppress or wake clients individually or the entire NAR. All receive queues can be
suppressed on the occurrence of a selected trigger, or the full NAR can be brought out of
suppress mode upon the occurrence of the appropriate trigger. A trigger can also be
programmed to toggle one or more clients between the suppressed and active states. Each
Suppress Trigger Control Register, shown in the following figure, is associated with one of
the triggers, and are used to determine the action taken, if any, upon the assertion of that
trigger. The suppress triggers are connected to the Sequence Processing Unit (SPU) action
unit.

The NAR_STCR are described in the following table. The set of clients connected to the
NAR is device specific. For a list of the clients that are connected to the NAR and their
corresponding NAR client index for the local suppress trigger, see the Calibration and
Debug configuration chapter which describes how the modules are configured.
