Linked data
• The bits of the upper (4-n) digits of the device designated by (D) become 0.
• The value of n can be designated at between 1 and 4.
• If n=0, there will be no processing, and the contents of device (D) will not change.
Operation error
• In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into SD0.
