■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.
• 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)
■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.
ASCII : ASCII code (th digit)
(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.
Value of (s) Data of (d) to (d)+3 Value of (s) Data of (d) to (d)+3
• 0H to FH • The upper byte of (d) is filled with 00H.
• (d)+1 and later remain unchanged.
• 10H to FFH • (d)+1 is filled with 00H.
• (d)+2 and later remain unchanged.

• 1000000H to
FFFFFFFH
• The upper byte of (d)+3 is filled with 00H. • 10000000H to
FFFFFFFFH
• (1): (d)+4 is filled with 00H when SM701 (Number of
output characters selection) is off. (d)+4 does not
change if SM701 (Number of output characters
selection) is on.
