hi,
I'm trying using ATmega128 on my project but I have no idea how should I use the pin "PEN". Datasheet says "By holding this pin low during a Power-on Reset, the device will enter the SPI Serial Programming mode. PEN has no function during normal operation" .Unfortunately I haven't seen any sample schematics for ATmeg128 ISP programming. does anyone has any idea?
