• An example of operation where digit specification is used for shift data (D) and the data (S) to be stored in the shift data is
shown below.
• In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into SD0.
• The sample program shifts the 9 words of data starting from D20 3 words to the left and transfers 3 words of data from D10
to the 3 words from D20.
