Example 2:
1. When SM606 is ON, the working mode of the instruction is the 8-bit conversion mode.
2. When X0.0 is ON, the six pieces of data in D0~D5 (eight bits as a group) are added up. The
sum is stored in D100, and the values of the parity bits are stored in D101.

Additional remark:
1. Suppose SM606 is ON. If S+n-1 exceeds the device range, the instruction is not executed,
SM0 is ON, and the error code in SR0 is 16#2003.
2. Suppose SM606 is OFF. If S+n/2-1 exceeds the device range, the instruction is not executed,
SM0 is ON, and the error code in SR0 is 16#2003.
