Hi I'm a beginner at assembly language and I have a piece of code I'm trying to understand. I understand most of it but I still am not sure what -(A7) or (A7)+ mean. I know An are address registers and so A7 is the last 32 bit address register (coldfire processor). But whats the -/+ before and after? Is it decrementing or incrementing? If so, what is being incremented or decremented? The address registers themselves? e.g. does -(A7) mean A6? Thanks.
