Explanations:
The instruction decodes the lower 4 bits (Hex data: 0 to 9, A to F) of source device S and stores the
decoded data in lower 8 bits of D so as to form a 7-segment display.
Program Example:
When X20 = ON, the content of the lower 4 bits (b0~b3) of
D10 will be decoded into the 7-segment display. . The
decoded results will be stored in Y20~Y27. If the source
data exceeds 4bits, still only lower 4 bits will be decoded.
