Introduction
10.1.2.4 ConnID Assignment
Each L3 initiator includes a unique 6-bit master connection identifier (MConnID) that is used to indentify
the source of a transfer request. Since AM335x contains more than 16 unique masters some masters will
appear identical to target firewalls.

These MConnIDs are generated within the OCP-WP module based on the H0, H1, and H2 configuration parameters.
NOTE: Instrumentation refers to debug type. SW instrumentation means that the master can write
data to be logged to the STM (similar to a printf()). HW indicates debug data captured
automatically by hardware. A '0' entry indicates no debug capability.
