TM4C1230D5PM: Trace connections

Part Number: TM4C1230D5PM
Other Parts Discussed in Thread: TM4C123

To use the trace functions on the XDS110 debug probe, what pins on the tm4c1230d5pm should be connected.

The JTAG pins have the same names as the pinout table 4 in the debugger document, but I don't know what pins to connect to EMU0-EMU4 of the dubber

  • Hi Jeffrey,

      There is no such pins (EMU0-EMU4) on TM4C123 MCU. In another word, TM4C123 does not have trace features that utilize these pins. Please find below link for additional information. On the JTAG connector you can leave them as NC for TM4C123 MCU.


    Q: What are the EMU0/1 pins used for?

    • A: The EMU0/1 pins can be used for cross-core triggering (ex: one device halts and signals the others to halt, see Advanced Event Triggering or, in some selected devices, these pins are used for Wait in Reset and transfer instrumentation and trace information. Please see the device datasheet/TRM for details.

    Q: What are the EMU2-x pins used for?

    • A: These are reserved for high speed instrumentation information and trace information.
