Explanation of function and operation
1. 16-bit operation (STR and STRP)
1) All digits (specified by
decimal point is added to the position specified by the device storing the number of digits of the decimal part
( S +1), and stored in

2) Set the number of all digits
3) Set the number of digits of the decimal part
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
5) Converted character string data is stored in
- As the sign, "space" (20H) is stored when the 16-bit binary data stored in
stored when the 16-bit binary data stored in
- When the number of digits of the decimal
part S +1 is set to any value other
1
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 S +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
