Embedded Debugger Implementation

SAMDA1 Xplained Pro contains an Embedded Debugger (EDBG) that can be used to program and debug the
SAMDA1J16A
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
Studio can be used as a front-end for the Embedded Debugger.
4.3.1

Serial Wire Debug

The Serial Wire Debug (SWD) uses two pins and a reset line to communicate with the target. For further information on
how to use the programming and debugging capabilities of the EDBG, see

Virtual COM Port

The Embedded Debugger acts as a Virtual Com Port gateway by using one of the

4.3.3

Atmel Data Gateway Interface

The Embedded Debugger features an Atmel Data Gateway Interface (DGI) by using either a SPI or I²C port.
The DGI can be used to send a variety of data from the
the DGI interface see
