The isolation jumper block J101 allows the user to connect or disconnect signals that cross from the XDS110 domain into the MSPM0G3708 target domain. This includes XDS110 SWD signals, application UART signals, 3.3V and 5V power, and reset.
| Jumper | Description |
|---|---|
| 5V | 5V rail from the USB. |
| 3V3 | 3.3V rail from the LDO. |
| RXD<< | Backchannel UART: The target MSPM0G3708 receives data through this signal. The arrow indicates the direction of the signal. |
| TXD>> | Backchannel UART: The target MSPM0G3708 sends data through this signal. The arrow indicates the direction of the signal. |
| NRST | Reset Signal. |
| SWDIO | Serial Wire Debug: SWDIO data signal. |
| SWCLK | Serial Wire Debug: SWCLK clock signal. |
| BSL | Invoke pin for bootstrap loader. Allows the XDS110 to invoke BSL. |
