The code is correct. Although I am wondering why registers r8-r13 are being
saved to the stack (different to the original 3.3.1 non-optimized code). Are the
rules for register usage in interrupt handlers going to be changed in 3.4?

BTW, I now agree to comment #1. Sibcalling optimization must be disabled in
interrupt handlers.
