can you pliz explain to me the instructions RRC(rotate accumulator right )and the instructions RLC(rotate accumulator left) and their usage especially in multiplication in an 8085 progamming language

[shabbir]

When you rotate the accumulator its actually a shifting and so shifting is actually results in devide multiiply by 2

e.g.
0110 = 6
Right shift = 0011 = 3 = 6/2
Left Shift = 1100 = 12 = 6x2

Thanks
