A master NIU ID (ConnID) is assigned to every module in the device. The ID uniquely identifies the master NIU for an interconnect transfer (see Table 14-10). The interconnect uses ConnID values for a number of purposes, including:
8-bit ConnID (hex) | 4-bit ConnID (hex) | Master NIU |

The 8-bit ConnID values are used by error decoding to distinguish the different initiators, see Section 14.2.3.8.5, Example for Decoding Standard/Custom Errors Logged in L3_MAIN. They are also used by the EMIF controller. The 4-bit ConnID values are used by the firewalls to allow or not an access to a slave NIU, see Table 14-18.
