■Operation of when SM705 (Number of conversion digits selection) is off
Hexadecimal ASCII data is stored in a fixed number of digits (8 digits) in (d) to (d)+3.

(1): 00H is stored in (d)+4 when SM701 (Number of output characters selection) is off. When it is on, the value in (d)+3 remains unchanged.
• The operation result to be stored in the device specified by (d) is processed as a 8-digit hexadecimal number. Therefore, 0
at the left side of the effective number of digits is processed as "0". (Zero padding)
Ex.
When 03AC625EH is stored in the device specified by (s)
(s)+1 (s)
0 3 A C 6 2 5 EH
■Operation of when SM705 (Number of conversion digits selection) is on
Hexadecimal ASCII data for the number of digits (up to 8 digits) without the leftmost "0" in the effective digits is stored right-
justified in (d).
The following figures show an example of a value of (s) and a value stored in (d).

• When the number of digits is less than the maximum number of digits (8 digits), 00H is stored in the end of the string
regardless of the status (on/off) of SM701 (Number of output characters selection). If the end of the string is the lower byte,
00H is also stored in the upper byte.
• When the number of digits is equal to the maximum number of digits (8 digits), 00H is stored in (d)+4 when SM701 (Number
of output characters selection) is off. (d)+4 does not change if SM701 (Number of output characters selection) is on.
