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.
