Invokes upgrade mode. No further communication is required.
Upgrading firmware on EDBG-based tools is not a publicly documented mechanism. Calling this protocol command will cause a response to be sent before communication ceases and the tool re-enumerates into its upgrade configuration. At this point atfw.exe (part of Atmel Studio) can be used to upgrade the firmware on the tool. Toggling power without upgrading will put the tool back into application mode.
