8.2 Debug Modes
To program external devices, use the debug connector to connect to a target board and set the debug mode to [Out]. The same con-
nector can also be used to connect an external debugger to the BGM220P Module on the kit by setting debug mode to [In].
Selecting the active debug mode is done in Simplicity Studio.
