High−level Instructions
3 − 183
Outline Converts ASCII code that expresses decimal digits to 32-bit data that
expresses the equivalent number.
For the FP0R/FPΣ/FP−X/FP0/FP−e, the P type high−level instruction
“P78 (PDABI)” is not available.

(*1) This cannot be used with the FP0 and FP−e.
(*2) This cannot be used with the FP0, FP−e, FP0R, FPΣ, FP−X.
(*3) With the FP0R, FPΣ,FP−X, FP2, FP2SH, and FP10SH, this is I0 to IC.
Explanation of example
Converts ASCII codes (10 bytes) that express decimal digits in data registers DT4, DT3, DT2, DT1 and DT0
to 32-bit data when trigger R0 turns on. The converted data is stored in data registers DT51 and DT50.
