*`UART TXD` pin is the serial output of the target device.
* On the target **DPP2 LoRa** the tracing pins `INT2` and `LED3` are shared with the SWD debug interface and can therefore not be used when forwarding the debug session. Similarly, `LED2` is shared with the SWO pin and must be configured in SWO mode if data tracing is enabled.
*`LED1` on the target **DPP2 LoRa** is connected to the `RFDIO1` pin of the SX1262 radio. As a consequence, `PA15` must be configured as an input pin.
