Atmel Data Gateway Interface

The Embedded Debugger features an Atmel Data Gateway Interface (DGI) by using either a USART or TWI
port. The DGI can be used to send a variety of data from the SAM4E to the host PC. For further information on
how to use the DGI interface see

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 SAM4E application
code. For further information on how to configure and use the GPIO monitoring features see
