I have a custom PCB with an Atmega 328 on it. The board is in a rack with other boards CPU i/O ect.
Of course when I switch off the rack power I lose my ICE power also. Can I provide a seperate ATMEL ICE voltage to the VTG that remains on when I switch the rack power off with the caveats above?
Currently the rack CPU and my board are kind of asyncronous when it powers up. I would like to have debug code ruinning when I power the rack.
