I've blown a couple AVR8515's that way, I don't know why exactly.
A series 4.7k resistor seems to solve the problem.
The timing is trickier than it looks. Some brands use 1-2mS others use
400uS-2mS
There may be more variants, but that's what I've seen in servos I've bought
in the last 8 months.
It's a brand thing.

I've got AVR routines at www.dontronics.com in the download dungeon
"getting started" .
