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.

SAM B11ZR pin Function Shared functionality
LP_GPIO_12 GPIO/SPI SS (Slave select) (SAM
B11ZR is Master) EXT1
LP_GPIO_13 SPI MISO (Master In, Slave Out) EXT1
LP_GPIO_11 SERCOM5 PAD[2] SPI MOSI (Master
Out, Slave in) EXT1
LP_GPIO_10 SERCOM5 PAD[3] SPI SCK (Clock Out) EXT1

SAM B11ZR pin Function Shared functionality
LP_GPIO_8 SDA (Data line) EXT1, Temperature Sensor
LP_GPIO_9 SCL (Clock line) EXT1, Temperature Sensor
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.

LP_GPIO_17 GPIO1 EXT1, EXT3
LP_GPIO_18 GPIO2 EXT1, EXT3
LP_GPIO_19 GPIO3 EXT3
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.
