Program Trace Synchronization
Messages for taken indirect branches and exceptions include how many sequential bytes were
executed since the last taken branch or exception, and the unique portion of the branch target
address or exception vector address. The unique portion of the branch is found by doing an
exclusively or on the branch target and the last sent UADDR / FADDR. Additionally, the cause
of the indirect branch is identified through an Event ID packet. Operations causing indirect
branches and their corresponding EVT-ID are shown below.
Table 9-34.
Note that subrotine returns are often accomplished by a mov pc, lr, popm or ldm instruction with
PC included in the argument list. This generates an EVT-ID of 0 instead of 1..

The unique portion of the branch target address for a taken
indirect branch or exception. Most significant bits that have a
value of 0 are truncated.
