AVR Samples - are they just a myth? I've never had trouble getting samples from Atmel, but it was always through my FAE. Atmel has always been very helpful to me and my company even though we were up front with...

finding average of signal I prefer the form:
new = (1-x)*(input - previous) + previous
Which trades a multiply for an add. Not a big deal with integers but can speed things up noticibly for floats.

NPCS lines for SPI on UC3 Also, by having automatic dedicated chip select lines allows running the whole setup via DMA which gives you the capabilty of crazy fast I/O with no lines of code.
According to the datasheets, UC3A chips have CPU revision 2 while the UC3B chips have CPU revision 1.
Crazy idea (more like insane). Do the MCUs in question have OCD? If so, perhaps the OCD unit could aid in performing these tests?

What industry conventions are you refering to? MS Windows uses higher number = higher priority and that's a pretty big market segment.
Can the assembler tell the difference by the size of the immediate (8 bit vs 16 bit)?

Also, R15 is the program counter so you can't use it as a general register.
Ground plane?
