The instruction will first convert binary data (S) into BCD code, and then shift and transmit the BCD code to achieve data allocation and combination. The BCD code of the source data (S) is shifted from the (N1) th bit to the (N2) th bit starting from the (N3) th bit of the data (D), while the BCD codes of the other bits of the destination data (D) remain unchanged. Then, the BCD code in data (D) is automatically converted into a binary number, which is the content of data (D). An error occurred when the BCD code value exceeded 9999.
