Q. Explain logical shift Micro-operations?

In logical shift data entering by serial input to left most or right most flip-flop (which depends on right or left shift operations respectively) is a 0. 

If we attach the serial output of a shift register to its serial input then we encounter a circular shift. In circular shift right or circular shift left information isn't lost however is circulated.
