Output Pin to 5V
Yes, what if one uC is trying to drive the line high while another is trying to drive the line low? This is called bus contention and leads to high power draw and possibly a dead...

Semiconductor timing reference?
I don't see what all the hubub about these magic frequencies are. I haven't had any problems with my UARTs while running them up to 115.2 kbps with my "unclean" clocks like 8, 12...

wear out AVRs?
I'll worry about bugs in my code long before I will ever worry about flash/EEPROM endurances and MTBFs!

"Low level"/"level" INT0 Power Down
mtaschl wrote:But PD2 can also fire PCINT18 and this will work in power-down-mode. It will fire at any edge, so you have to check the level by software after wakeup.Good point!...

"Low level"/"level" INT0 Power Down
You can't wake from power down on an edge, the edge detection needs a clock to work. The only way you can use external interrupts in power down mode is by using a low level...
