(*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
The higher and lower bytes of data register DT0 are exchanged when trigger R0 turns on.
