Hi,
I am going to overclock Atmega16L to 12MHz. I can do that when the JTAG header is attached. However, when it is detached, the program seems to be not working. I have tried to shut down the power of the emulator and it still works when the JTAG header is attached. I do not understand why this strange case happens. Could anyone talk to me why this happens? As I need to use 3.3V, I need to use Atemga16L.
