Target Design Considerations for Using the XDS560 Emulation Pod
Additionally, Texas Instruments adds two more signals, used for advanced
emulation capability, to the JTAG header.
These signals, shown in Table 3−3, provide the capability to perform High-
Speed Real-Time Data eXchange (RTDX), benchmarking, software profiling
and multi-processor emulation with inter-processor breakpoint capabilities.

The TI advanced emulation JTAG signals are used by the XDS560 to perform
clocking capabilities when performing software benchmarking and software
profiling.
Other capabilities include:
- Assistance with multi-processor debugging.
- As an output and driven low by a device as a result of breakpoint conditions
being met.
- As inputs monitored in the debugging logic, which allows one core to set
the EMU signal, and another device to break as a result.
- On an HS−RTDX enabled target device, Each EMU signal can support an
RTDX transmit and receive data channel.
