Converts decimal ASCII data to 16-bit data (Data end: ',')
① ASCII data (reverse direction)
：
：
00020101
② Conversion starting position (1) → [S2]+1 bytes
③ Amount of conversion data (2) → 2 data separated by a comma
[S2]
③ Amount of data to be converted = 2
DT0 to DT2: "1234," → DT100: U 1234 (H 04D2)
DT3 to DT5: "5678," → DT101: U 5678 (H 162E)

Example 5) Converting two hexadecimal ASCII data (separated by commas) to two
16-bit binary data (hexadecimal)
The conversion starts from the high byte of DT0. If there is no specification for the number of
digits, it is processed considering commas as the data delimiter. It is converted in reverse
direction (the low word side of [S2] is considered as high-order numerical data).

Example 6) Converting two decimal ASCII data (4 digits) to two 16-bit BCD data (if
there is a comma at the end of the data)
The conversion starts from the low byte of DT0. If the data includes a comma, it is processed as
a data delimiter even if the number of digits is less than specified. It is converted in reverse
direction (the low word side of [S2] is considered as high-order numerical data).
