Web11 Jul 2024 · The address when SP is taken as the offset denotes the memory location where the top of the stack lies. Therefore, the effective address for both these cases is: (SS X 10H) + SP = 3640H X 10H + 1735H = 36400H + 1735H = 38135H (SS X 10H) + BP = 3640H X 10H + 4826H = 36400H + 4826H = 41226H.
