I am writing an assembly language subroutine which is callable form C. Therefore I cannot use the index register I7, but I7 would be the only register which modify the STKY register or could raise and interrupt at a circular buffer overflow. Did I understand this correct?


How one can detect a circular buffer overflow for registers I0 to I6?
