The result is thenplaced in the A accumulator. The net effect of this operation is to divide the content ofXO by 2 3 and add the result to the accumulator. An alternate interpretation is that XO isright shifted 3 places and filled with the sign bit (0 for a positive number and 1 for a negativenumber) and then the result is added to the accumulator.Instruction Format 2:MAC(±)S,#n,DOpcode 2:23 16 15 8 7 o10 0 0 0 0 0 0 11000 S S ss sl1 1 a a d k 1 01Instruction Fields:S QQ Sign k D dY1 0 0 + 0 A 0XO 0 1 1 B 1YO 1 0X1 1 1
