3.2.2 EDBG Interface

The Xplained Pro Analog Module (XAM) is connected to the EDBG with the following interfaces:

• I²C: This is used to control and configure the XAM
• SPI: Current measurement data is streamed to the EDBG via this interface. This is a one-way data transfer channel from the XAM to the EDBG.
• SWD: The MCU in the XAM is programmed via SWD from the EDBG
• GPIO: At least one GPIO that is connected to the EDBG from the target MCU is also connected to the current measurement unit to enable the user to sync current measurements with his application
• Clock sync: Synchronization signal to synchronize ADC measurements with EDBG
• Reference clock: Reference clock for the XAM
