Explanation:
1. The 16-bit values in the registers specified by S~S+(n-1) are divided into groups (four bits as a
group), and every group which is composed of b0~b3 is stored in the register specified by D.

2. The operand n should be within the range between 1 and 4.
Example:
Suppose the values in D0~D3 are 16#1234, 16#5678, 16#8765, and 16#4321 respectively. When
M0 is enabled, the instruction UNI is executed. The values in D0~D3 are divided into groups (four
bits as a group), and every group which is composed of b0~b3 is stored in D10.
