4.6.2. Virtual COM Port
The Embedded Debugger acts as a Virtual Com Port gateway by using one of the ATSAME70Q21
UARTs. For further information on how to use the Virtual COM port, see Embedded Debugger on page 7.

4.6.3. Atmel Data Gateway Interface
The Embedded Debugger features an Atmel Data Gateway Interface (DGI) by using either a SPI or I
2
C
port. The DGI can be used to send a variety of data from the ATSAME70Q21 to the host PC. For further
information on how to use the DGI interface, see Embedded Debugger on page 7.

Four GPIO lines are connected to the Embedded Debugger. The EDBG can monitor these lines and
timestamp pin value changes. This makes it possible to accurately timestamp events in the SAM E70
application code. For further information on how to configure and use the GPIO monitoring features, see
Embedded Debugger on page 7.
