17.1. About the AHB trace macrocell interface

The AHB Trace Macrocell (HTM) interface enables a simple connection of the AHB trace macrocell to the processor. It provides a channel for the data trace to the HTM.

To use the HTM interface, the HTM_PORT_ENABLE define must be uncommented in CM3Defs.v before implementation. TRCENA must also be set to 1 before you enable the HTM to enable the HTM port to supply trace data.
