14.3.1. Branch status signal

A branch status signal, BRCHSTAT, is exported on the Embedded Trace Macrocell (ETM) interface that indicates if there are any branches in the pipeline. A prefetcher, for example, can use this to prevent prefetching if a branch is about to be fetched. For more information about the branch status signal, see Chapter 16 Embedded Trace Macrocell Interface.
