ASCII data
(Note 1) For "n", specify the number of digits. Conversion is performed for every "n" digits. However, data
separation occurs wherever a comma (",") appears.
(Note 2) When omitting "n", insert a comma (",") to separate the data.
(Note 3) When there is a comma followed by another comma, it is converted to the value "0". Example: When
the number of the data is three, ",," is processed as the data "0, 0, and 0".

Specification of conversion method [N]
Conversion method [N] should be specified in a Hex format (8 digits) in the 32-bit area.
[N] =
Amount of data to be converted
H1 to H FFFF (1 to 65535)

Conversion starting position
H0 to H FF (Conversion)
Specify the header of the character string to convert from the
relative position of the low byte of [S2]. The round numbers
in the following diagram indicate the relative position.
The character string to be converted starts from relative
position ① for H00 and from relative position ② for H1.

Conversion example
Example 1) Converting two hexadecimal ASCII data (4 digits) to two 16-bit binary
data (hexadecimal)
The conversion starts from the low byte of DT0. It is converted in reverse direction (the low
word side of [S2] is considered as high-order numerical data).

Conversion direction
H00: Forward direction
H01: Reverse direction
Specify a conversion direction. Forward direction can only be
specified for hexadecimal data (control string %x) or BCD data
(control string %b). For all other data formats, reverse direction
is specified (fixed).
