As shown above, the command code, source and destination in basic No. of steps for the command
are equivalent to one step each. Only some of the command codes and the 32-bit command constant
K or H use two steps.
(Note) If the constant value in the DMOV or D* command, etc., is small, a display in which there is a
space equivalent to one step will occur between the source (S) and destination (D) or
between the source (S2) and destination (D). (Section marked with * in diagram.
