Embedded Debugger Implementation

ATmega4809 Xplained Pro contains an Embedded Debugger (EDBG) that can be used to program and
debug the ATmega4809 using the UPDI interface. The Embedded Debugger also includes a Virtual Com
port interface over UART, a Data Gateway Interface over SPI, and I
ATmega4809 GPIOs. Atmel Studio can be used as a front-end for the Embedded Debugger.
