33.3 Features
The NDI module of the MPC5604B is compliant with Class 2 of the IEEE-ISTO 5001-2003 standard, with
additional Class 3 and Class 4 features available.The following features are implemented:
• Program trace via branch trace messaging (BTM). Branch trace messaging displays program flow
discontinuities (direct and indirect branches, exceptions, etc.), allowing the development tool to
interpolate what transpires between the discontinuities. Thus static code may be traced.
• Ownership trace via ownership trace messaging (OTM). OTM facilitates ownership trace by
providing visibility of which process ID or operating system task is activated. An ownership trace
message is transmitted when a new process/task is activated, allowing the development tool to
trace ownership flow.
• Watchpoint messaging via the auxiliary pins
• Watchpoint trigger enable of program trace messaging
• Auxiliary interface for higher data input/output
— 4 message data out pins
