Hi i'm reading from adc register memory using assembly language each instruction that uses this register takes 3 clock cycles although it should take 1 clock cycle like the instruction : AND AL,@8,#FF00 where @8 is the address of adc Result register no. 1 using direct addresssing mode. this instruction should take 1 clock cycle according to the datasheet of the mcu. but using clock profile it took 3 clock cycles and i need to minimize the no. of cycles in the ISR to prevent interrupt losses.
