4.3 Embedded Debugger Implementation

SAM4N Xplained Pro contains an Embedded Debugger (EDBG) that can be used to program and debug the ATSAM4N16C using Serial Wire Debug (SWD). The Embedded Debugger also include a Virtual Com port interface over UART, an Atmel Data Gateway Interface over SPI and TWI and it monitors four of the SAM4N GPIOs. Atmel Studio can be used as a front end for the Embedded Debugger.
