Example 1:
When X0.0 is ON and SM616 is OFF, the instruction rotates the values of the bits in the 16-bit registers D0–D2 to the left,
and stores the operation result in the 16-bit registers D20–D22. The value of the bit marked ※ is transmitted to the carry
flag SM614.
Before the rotation
is executed
