2.3.1 Isolation Jumper Block

The isolation jumper block J14 allows the user to connect or disconnect signals that cross from the XDS110 domain into the MSPM0L2117 target domain. This includes the XDS110 SWD signals, application UART signals, 3.3V and 5.5V power, reset, and a BSL invoke.

RXD<<Backchannel UART: The target MSPM0L2117 receives data through this signal. The arrows indicate the direction of the signal.
TXD>>Backchannel UART: The target MSPM0L2117 sends data through this signal. The arrows indicate the direction of the signal.

SWCLKSerial wire debug: SWCLK clock signal
BSLInvoke pin for bootstrap loader. Allows the XDS110 to invoke BSL.

During normal prototyping most shunts are populated. However, there are some scenarios where a user needs to open these connections:

  • To remove any and all influence from the XDS110 debug probe for high accuracy target power measurements
  • To control 3.3V and 5V power flow between the XDS110 and target domains
  • To expose the target MCU pins for other use than onboard debugging and application UART communication.
  • To expose the programming and UART interface for the XDS110 so that the XDS110 can be used for devices other than the onboard MCU.
