4.3 Embedded Debugger Implementation

XMEGA A1U Xplained Pro contains an Embedded Debugger (EDBG) that can be used to program and debug the ATxmega128A1U using the Program Debug Interface (PDI). 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 XMEGA GPIOs. Atmel Studio can be used as a front end for the Embedded Debugger.
