<DIV><FONT face=Arial size=2>Nut/os is a cooperative multitasking so I
don't understand why in context switching ALL registers are saved. In my
opinion you have only to save R28/R29 (Y reg in ICCAVR). The other
registers are saved by compiler or you don't need to save
them (volatile regs).</FONT></DIV>
