When X0.0 is ON, SM616 is ON. The values of the bits in the 16-bit registers D0~D2 are rotated to

the right, and the operation result is stored in the 16-bit registers D20~D22. The value of the bit

marked ※ is transmitted to the carry flag SM614.

Additional remark:

If S+n-1 or D+n-1 exceeds the device range, the instruction is not executed, SM0 is ON, and

the error code in SR0 is 16#2003.

If n is less than 1, or if n is larger than 256, the instruction is not executed, SM0 is ON, and the

error code in SR0 is 16#200B.

SM614: It is the carry flag for the matrix rotation/shift/output.

SM616: It is the direction flag for the matrix rotation/shift.
