High−level Instructions
3 − 300
Outline Counts the number of bits in the on (1) state in specified 32-bit data.
For the FP0R/FPΣ/FP−X/FP0/FP−e, the P type high−level instruction
“P136 (PDBCU)” is not available.

(*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
Counts the number of bits in the on (1) state in data register DT11 and DT10 when trigger R0 turns on. The
number of on (1) bits is stored in data register DT20.
