Atmel Data Gateway Interface

The Embedded Debugger features an Atmel Data Gateway Interface (DGI) by using either UART or TWI. The DGI can be used to send a variety of data from the SAM G53 to the host PC. For further information on how to use the DGI interface, see the EDBG user guide.

Four GPIO lines are connected to the Embedded Debugger. The EDBG can monitor these lines and time stamp pin value changes. This makes it possible to accurately time stamp events in the SAM G53 application code. For further information on how to configure and use the GPIO monitoring features, see the EDBG user guide.
