Explanation:
1. The 16-bit value in the register specified by S is divided into four groups (four bits as a group),
and these groups are stored in the low four bits in every register (The registers range from D to
D+(n-1).).

2. The operand n should be within the range between 1 and 4.
Example:
Suppose the value in D0 is 16#1234. When M0 is enabled, the instruction DIS is executed. The
value in D0 is divided into four groups (four bits as a group), and these groups are stored in the low
four bits in every register (The registers range from D10 to D13.).
