4.2.2 EDBG Interface

The 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 unidirectional channel from the XAM to the EDBG.
  • SWD: The MCU in the XAM is programmed via SWD from the EDBG.
  • Clock sync: Signal used to synchronize ADC measurements with the EDBG.
  • Reference clock: Reference clock for the XAM.
