Backward compatible to standard JTAG IEEE 1149.1-2001 test access port (TAP) interface
Support for boundary scan testing
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.
Data Trace via Data Write Messaging (DWM) and Data Read Messaging (DRM). This provides the capability for the
development tool to trace reads and/or writes to selected internal memory resources.
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.
Run-time access to embedded processor memory map via the JTAG port. This allows for enhanced download/upload
capabilities.
Watchpoint Messaging via the auxiliary pins provides visibility when debugging.
Watchpoint Trigger enablement of Program and/or Data Trace Messaging enhances debug capability.
