5.2.2 Lite XDS110 (MSPM0 LaunchPad™ kit)

The MSPM0 LaunchPad kit include the XDS110 (Lite) circuit. You can also use this debugger to download your firmware into MSPM0 device. Figure 5-5 shows the LP-MSPM0C1104 circuit.

2.54-mm probe: This port supports the SWD protocol and includes a 5-V or 3.3-V power supply. You can connect SWDIO SWCLK 3V3 GND to the board and download firmware into the MSPM0C device.

Note:
  • Standard XDS110 support level shift for debug ports, XDS110 just support 3.3v probe level.
  • TI does not recommend using the XDS110 to power other devices except the MSPM0C MCU. The XDS110 integrates an LDO with limited current drive capability.
