I am using Atmega1281 and planning to program the device with one more micro controller.
Using AVR Studio 4.12.472, Service Pack 2, integrated with AVR GCC.
I could see in the option “AVR studio -> Tools -> Program AVR -> Connect -> Disconnected Mode -> “ as
“ ? serial program downloading (SPI) enabled; [SPIEN = 0]”.
What does the ? mean, can I do Serial program downloading with SPI……please clarify?
