4.3.3 Data Gateway Interface
The Embedded Debugger features an Data Gateway Interface (DGI) by using either an SPI or I²C. The
DGI can be used to send a variety of data from the ATSAMB11ZR to the host PC.

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 SAM B11ZR
application code.

4.3.4 SAM B11ZR Xplained Pro XAM Configuration
On the SAM B11ZR Xplained Pro the MCU and the MCU peripherals (e.g. extensions) are powered by
their own regulator, as shown in the following figure. All other parts of the board, mainly the embedded
debugger and accompanying Xplained Pro Analog Module (XAM), are powered from a separate
regulator. The current to the MCU and peripherals can be measured by connecting them to the XAM
output through jumper settings.
