	MD (multiplier/division register) « on: October 05, 2014, 06:51:58 AM »

Hi, guys!
Are there any instructions in ASM that indirectly gets data from MD register? What I mean is mulu for example stores data in MD. And I see no direct calls to MD, MDL, MDH. Where could be the instruction that gets data from this register?

No, your SFR's aren't labeled.

Could there be that results from multiplication and division are stored in word_FE0C and/or word_FE0E? they always show up after mul ops in my file. Maybe through them I can access MDH and MDL or something???

You are looking at MDH and MDL, they just aren't labeled.
