# Shift microoperations and examples.

Shift micro operations are involved in shifting of bits of a register. These operations are categorized into three groups, `logical`

shift, `circular`

shift and `arithmetic`

shift.

**Logical shift micro- operations**: These operations are associated with shift of data bits towards left or right and allowing a serial bit stream to occupy vacated bit positions.

So an example of shift left microoperations on register A = 1001 is shown below: (Reverse of below will give shift right)
