Connecting to Data Gateway Interface

The Atmel-ICE supports a limited Data Gateway Interface (DGI) when debugging and programming is not in use.
Functionality is identical to that found on Microchip Xplained Pro kits powered by the Microchip EDBG device.
The Data Gateway Interface is an interface for streaming data from the target device to a computer. This is meant as
an aid in application debugging as well as for a demonstration of features in the application running on the target
device.
DGI consists of multiple channels for data streaming. The Atmel-ICE supports the following modes:
• USART
• SPI
