Hi guys, 

              Newbie here. I'm working with the SAML21 Xplained pro board.


1. Please let me know as to <b> why the EDBG_ADC0 line is connected to the TARGET_VOLTAGE (Power Supply )and TARGET_VOLTAGE_MEASUREMENT (U_SAML21_Xplained_Pro_current_measurement)</b>.

2. You can find this particular connection on the 1st page of the design document I've attached.

3. I'm also attaching the User Guide of the Embedded Debugger where they must have provided information, but obviously haven't (or I missed it).

4. I'm also attaching the User Guide of the SAML21 Xplained Pro where they have discussed the Embedded Debugger but again haven't gone into the details of the connection I mentioned above.
