Introduction
to trace ownership flow.
— Program trace via branch trace messaging (BTM). Branch trace messaging displays program
flow discontinuities (direct branches, indirect branches, exceptions, etc.), allowing the
development tool to interpolate what transpires between the discontinuities. Thus, static code
may be traced.
— Watchpoint messaging (WPM) via the auxiliary port
— Watchpoint trigger enable of program and/or data trace messaging
— Data tracing of instruction fetches via private opcodes
