Operation Error
(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. (Error code: 4100)
• The range 2
n
bits from exceeds the range of the relevant device.
(Error code: 4101)
• All data 2
n
bits from is "0". (Error code: 4100)
Program Example
(1) The following program encodes the 3 bits from M10 when X20 is ON, and stores the results
at D8.
