 Essential condition: nЉ16 (16-bit command), nЉ32 (32-bit command).
 The (D) RCR command is used to assign the (32) 16-bit data with the
attached carrying flag (M1022) to conduct the rotate-to-the-right
command.
 It is generally advised to use the pulse wave contact to drive this
command, otherwise, it will keep going on and on.
 When M, Y, S are assigned to serve as the bit operand, only K4 (16-bit)
and K8 (32-bit) are effective, e.g. K4M0, K8Y0.
 Command Motion Explanation
 When X0 goes from OFFШON, the 16 bit data of D10, along with the
attached carrying flag (M1022), will rotate 4 bits to the right, as shown
in the diagram, and b3 that located at D10 originally will then be moved
to the carrying flag M1022, and that the original contents of the
carrying flag M1022 will be moved to the bit of b12.
