Silicon Labs EFM32: What are the minimum pins required for debugging/programming?

EFx32

Of the pins drawn out to the Debug Connector of the Starter Kit, use the following 6 pins.
SWCLK, SWDIO, SWO, #RESET, VTARGET, GND
Of these, 2 pins, SWO and #RESET, are optional, and the remaining 4 pins must be used.
If SWO is not connected, Energy Profiler will not be able to use the function to jump from current value to source code. Also, the SWO terminal of energyAware Commander cannot be used.
If #RESET is not connected, the debug unlock function cannot be used. As for #RESET, I highly recommend using it.
