4.3.3
Atmel Data Gateway Interface
The Embedded Debugger features an Atmel Data Gateway Interface (DGI) by using either a SPI or TWI port.
The DGI can be used to send a variety of data from the SAM4S to the host PC. For further information on how
to use the DGI interface see
Table 4.15. DGI interface connections when using SPI
Table 4.16. DGI interface connections when using TWI
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 SAM4S application
code. For further information on how to configure and use the GPIO monitoring features see
