3.10. 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 Atmel Xplained Pro kits powered by the Atmel 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 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
Table 3-9. Atmel-ICE DGI USART Pinout
AVR port SAM port DGI USART pin Description
3 6 TX Transmit pin from Atmel-ICE to the target device
4 1 VTG Target voltage (reference voltage)
8 7 RX Receive pin from the target device to Atmel-ICE
9 8 CLK USART clock
2, 10 3, 5, 9 GND Ground
Table 3-10. Atmel-ICE DGI SPI Pinout
AVR port SAM port DGI SPI pin Description
1 4 SCK SPI clock

4 1 VTG Target voltage (reference voltage)
5 2 nCS Chip select active low
9 8 MOSI Master Out Slave In
2, 10 3, 5, 9 GND Ground
Important: SPI and USART interfaces can not be used simultaneously.
Important: DGI and programming or debugging cannot be used simultaneously.
