Explanation of function and operation
1. 16-bit operation (STR and STRP)
1) All digits (specified by ) of 16-bit binary data stored in are converted into ASCII codes while the
decimal point is added to the position specified by the device storing the number of digits of the decimal part
( +1), and stored in and later.
2) Set the number of all digits in the range from 2 to 8.
3) Set the number of digits of the decimal part +1 in the range from 0 to 5.
Make sure to satisfy "Number of digits of decimal part <= (Number of all digits -3)".
4) 16-bit binary data to be converted stored in should be within the range from -32768 to +32767.
5) Converted character string data is stored in and later as shown below.
- As the sign, "space" (20H) is stored when the 16-bit binary data stored in is positive, and "-" (2DH) is
stored when the 16-bit binary data stored in is negative.
- When the number of digits of the decimal
part +1 is set to any value other
than "0", the decimal point "." (2EH) is
automatically added in "number of digits of
decimal part + 1"th digit.
When the number of digits of the decimal
part +1 is set to "0", the decimal
point is not added.
- When the number of digits of the decimal
part +1 is larger than the number of
digits of 16-bit binary data stored in
, "0" (30H) is automatically added,
and the data is shifted to the right end
during conversion.
