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.
