SAM E54 Xplained Pro contain an Embedded Debugger (EDBG) that can be used to program and debug the ATSAME54P20A using Serial Wire Debug (SWD). The Embedded Debugger also includes a Virtual Com port interface over UART, a Data Gateway Interface over SPI, and I2C, and it includes four of the SAM E54 GPIOs. The kit also includes an XAM extension processor to the Embedded Debugger for on-board current measurement. Atmel Studio can be used as a front end for the Embedded Debugger.
