Yes, this is always true. Also for the 128. Another thing to think of is the
JTAG Enable. Did cost me some hours... Table 118/119 in pdf-descriptions of
the 128 tells you all this, but if you don't come to page 285 of the file -
well, I don't want to remember.

Hi all,
I have just began a new design around mega64 (AVR Atmel) and i spent a
long day on a strange mega64 behaviour because it was shipped with mega103
compatibilty mode enable in Extended fuse bits. Is that always true ?
After that pb resolved, i found another strange thing, mega64 always
programmed very well (uisp or sp12 dongles) even PEN is left unconnected.
Are there another important thing to do with mega64 or 128 ?
Have you some advice about ?
Habib
