Xinje XD5 - Rotation Shift Left [ROL], Rotation Shift Right [ROR]

132
After executing LSL once, the lowest bit is filled with 0; the last bit is stored in carry flag.
LSL meaning and operation are the same to SHL.
After executing LSR once, the highest bit is filled with 0; the last bit is stored in carry flag.
LSR and SHR are different, LSR add 0 in the highest bit when moving, SHR all bits are
moved.
