Processing details
• These instructions convert the decimal ASCII data in the device numbers specified by (s) and later to 32-bit binary data,
and store the converted data in the device specified by (d).

• The ASCII data that can be specified by (s) to (s)+5 is -2147483648 to +2147483647 for signed data, and 0 to 429496729
for unsigned data. The data stored in the high-order byte of (s)+5 is ignored.
• As signed data, "20H" is stored if the ASCII data is positive, and "2DH" is stored if the data is negative. (If a value other than
"20H" and "2DH" is set, the data will be processed as positive data.) (DABIN(P))
• A value "30H" to "39H" can be set in the each place of the ASCII code.
• If a value "20H" or "00H" is set, the value will be processed as "30H".

Error code Description
(SD0/SD8067)
2820H The device specified by (s) exceeds the corresponding device range.
3401H The signed data is other than 20H, 2DH.
A value specified by (s) to (s)+2 for each place of the ASCII code is other than "30H" to "39H", "20H", and "00H".
The ASCII data in the device specified by (s) to (s)+5 is out of the valid range (-2147483648 to +2147483647) (when a signed data is
specified).
The ASCII data in the device specified by (s) to (s)+5 is out of the valid range (0 to 4294967295) (when unsigned data is specified).
