Explanation of example
Converts BCD code that express a 4-digit decimal number (4-digit BCD H code) stored in data register DT0 to
ASCII code when trigger R0 turns on. The converted data is stored in data registers DT10 and DT11.

Description
Converts the BCD code starting from the 16-bit area specified by S1 to ASCII code that expresses the
equivalent decimals as specified by S2. The converted result is stored in the area starting from the 16-bit area
specified by D.
A maximum of four bytes (8−figure of data) can be converted.
S2 specifies the number of source data bytes and the direction of converted data (normal/reverse).
The data length when converted to ASCII code becomes double the BCD source data.
