■Setting method of (s) for when SM705 (Number of conversion digits selection) is on
Set hexadecimal 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 (8 digits).
The following table lists the setting method of (s).
• The ASCII data in the device specified by (s) to (s)+3 is within the range from 00000000H to FFFFFFFFH.
• The data of (s)+4 or later is ignored.
• A value from 30H to 39H and 41H to 46H can be set in each place of ASCII code.
• If a value 00H is set in each place of ASCII code, the value will be processed as the end of the hexadecimal ASCII data.
