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
