High−level Instructions
3 − 105
Outline Subtracts one BCD data item that expresses an 8-digit decimal number
(8-digit BCD H code) from another (minuend).
For the FP0R/FPΣ/FP−X/FP0/FP−e, the P type high−level instruction
“P46 (PDB−)” 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.
