High−level Instructions
3 − 101
Outline Adds two BCD data items that express 8-digit decimal numbers
(8-digit BCD H codes) and stores the result in the specified area.
For the FP0R/FPΣ/FP−X/FP0/FP−e, the P type high−level instruction
“P43 (PDB+)” is not available.

S1 8-digit BCD equivalent constant or lower 16-bit area for 8-digit BCD data (for
augend)
S2 8-digit BCD equivalent constant or lower 16-bit area for 8-digit BCD data (for
addend)

(*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.
