65.4.2.1 Source filter register (NAR_SFR)
The MSP can be configured to accept or exclude messages from up to four sources. The
sources which are to be filtered are programmed in the source filter register (NAR_SFR) as
shown in the following figure. This register should only be set in the BD NAR because
partitioning is not supported in the PD NAR.

The NAR_SFR is described in the following table. The source trace IDs, that are compared
to the source filter fields (SFn), are device specific. For a list of the clients that are
connected to the NAR and their corresponding Nexus source trace IDs, see the Calibration
and Debug configuration chapter which describes how the modules are configured.
