 Operation errors
 In the following cases, an arithmetic error occurs, the error flag (SM0) turns ON, and an error code is stored at SD0.
- The ASCII code of each position designated by (S) to (S+3) is a value other than "30H" to "39H" and "41H" to "46H".
(Error code: 34)
- The range of the device designated by (S) exceeds the relevant device range. (Error code: 82)
 Program example
 The following program converts the 4-digit hexadecimal ASCII data set to D20 and D21 to a BIN value, and stores the
result of the conversion at D0.
