High−level Instructions
3 − 298
Outline Counts the number of bits in the on (1) state in the specified 16-bit data.
For the FP0R/FPΣ/FP−X/FP0/FP−e, the P type high−level instruction
“P135 (PBCU)” 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.
(*4) With the FP0R, FPΣ,FP−X, FP2, FP2SH, and FP10SH, this is ID.
Explanation of example
Counts the number of bits in the on (1) state in data register DT10 when trigger R0 turns on. The number of on
(1) bits is stored in data register DT20.
