■Setting method of (s) for when SM705 (Number of conversion digits selection) is on
Set decimal ASCII data with a desired number of digits (including 00H (NULL code)) in (s). Note that 00H (NULL code) is not
required to be set for the maximum number of digits (4 digits).
The following table lists the setting method of (s).
Value to be set Data of (s) to (s)+1
in (s)
• 0 to 9 • Set 00H in the upper byte of (s)+0.
• The data of (s)+1 or later is ignored.
b15

(s)+1
• 100 to 999 • Set 00H in the upper byte of (s)+1.
• The data of (s)+2 or later is ignored.

• The ASCII data in the device specified by (s) to (s)+1 is within the range from 0 to 9999.
• The data of (s)+2 or later is ignored.
• A value from 30H to 39H can be set in each place of ASCII code.
• If a value 20H is set in each place of ASCII code, the value is processed as 30H. If a value 00H is set, the value is
processed as the end of the decimal ASCII data.
