High−level Instructions
3 − 278
Outline Rotates a specified number of bits in the specified 16-bit data to the right
together with carry flag data.
For the FP0R/FPΣ/FP−X/FP0/FP−e, the P type high−level instruction
“P122 (PRCR)” 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
Rotates 4 bits in data register DT0 together with carry flag data “1” to the right when trigger R0 turns on.
