I have new raise function form AD when help me to use one nesting software interrupt, but now I have a problem when I use several (more than one) nesting software interrupts and background is done SDRAM butterfly test, but test is done with error, but SDRAM has correctly data.

The mistake happens:
1) when data is different from index or
2) when index is greater SDRAM_SIZE and different from data.

Now my develop is stop.

And I think that I must refused nesting software interrupts, because compiler has mistakes when saving registers
