The SAM G53 Xplained Pro contains an Embedded Debugger (EDBG) that can be used to program and debug the ATSAMG53N19 using Serial Wire Debug (SWD). The Embedded debugger also provides a Virtual Com port interface over UART, an Atmel Data Gateway Interface over UART and TWI, and it monitors four of the SAM G53 GPIOs. Atmel Studio can be used as a front end for the Embedded Debugger.
