Notes on operand usage:
K4 (16-bit) is only valid if the operand D is designated as KnY or
KnM.
n operand n=K1-K16 (16-bit)
 D: Device to be rotated. n: Number of bits for one rotation.
 Rotates the device designated by D to the right n bits.
 Generally use this command as a pulse execution type command (RORP).
 When X0 switches OFF to ON, 4 of the 16 bits in D10 specify a right rotation; the
content of the bit indicated with * (see figure below) is sent to the carry flag signal
M1022.
