(1) 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 value of n is not in the 0 to 8 range.
• The range 2
• All data 2
Program Example
(1) The following program encodes the 3 bits from M10 when X20 is ON, and stores the results
at D8.
